Here the trick part is "the bat cost 1 dollar more than the ball" Which means, the ball cost is also there in the bat plus 1 dollar.. so if the ball cost $0.10 then the bat would cost $1.10 and total would be $1.20 dollars which is not the right answer.
statement 1: bat+ball=1.10, statement 2: bat=1+ball put statement 2 in 1: 1+2ball=1.10 that means ball=0.10/2 => 0.5 cents i also did not understadn directly but instead like this.
To people like me : Let the cost of the ball be "B" in dollars. According to the information given, the bat costs $1 more than the ball, so the cost of the bat would be "B + $1." Now, we know that together, the bat and the ball cost $1.10. So, we can set up an equation: B + (B + $1) = $1.10 Combining like terms: 2B + $1 = $1.10 Subtract $1 from both sides of the equation: 2B = $0.10 Now, divide by 2: B = $0.10 / 2 = $0.05 So, the cost of the ball is $0.05 or 5 cents.
The thing about finding new patterns when you hit a wall is so true. I used to have trouble solving certain problems and then I found out about dictionaries and tuples. I was able to solve so many more after it. Need to find more patterns again. Thank you!
Let's say the cost of the ball is x. Since the bat costs $1 more than the ball, the cost of the bat is x + $1. The total cost of the bat and the ball together is $1.10, so we can set up the equation: x + (x + $1) = $1.10 Combine like terms: 2x + $1 = $1.10 Subtract $1 from both sides: 2x = $0.10 Divide both sides by 2: x = $0.05 So the ball costs $0.05, or 5 cents!
See I made it really simple... Instead of bat and ball we use different question... And also won't be using the word more than ($1 more than the ball) that stupid line causes all the confusion... We will use extra instead of more ok.. So let's say u tell ur friend Me : I got 20 rs extra from my uncle compared to aunty ... And when ur friend says Friend : Ok so how much u got n*gga And u say Me : I ain't black ni*gga I got 30rs in total and he says ok u ain't gettin pass me with that hand it over ok jokes aside... From the total 30, 20 is extra which means 20 is out of the league it can't be compared and from the remaining 10 we start the comparison we say okay 5 from lovely uncle and 5 from broken aunty we add the extra 20 we got 25... Me : I ain't forgetting my hero uncle.. Friend : what about ur aunty ma maan Me : Who Aunty...
to be able to spot the patterns you need to be exposed to a large dataset, which means you have to solve enough problems to gain that knowledge. And that is far from enough because if you do it slightly differently than the optimized solution there will be tons of edge cases to be considered.

Question, open to anyone, lets say the brain gets trained, interview is cracked and the job is offered as well, how often do engineers in FAANG companies actually come across these kind of challenges in their day to day life working in one of these companies? PS: I know a fperson who works in one of the FAANG and described codebase of one of their most popular product which gets offered to their customers where the class file seemed to contain over 1000 lines of code with single method averaging over 300 lines and no documentation
took me some thinking between both fast and slow brain to get to a bat costing $1.05 and a ball costing $0.05. When solving things with the fast brain, sometimes it takes one on a journey with their slow brain to make sure they got it right only to find oneself doubting self and repeat checking with the slow brain; only to confuse oneself! At least, that's what I experience when I try to do things my fast brain does with the slow brain!
Your content is soo aaawsome!!👌🏻... Trust me your videos not only gives me a good solution to my issues as a developer but also gives me motivation boost ❤️
Hard problems also involves applying some trick which is not always obvious.Average students can not think of them immediately. Can you please tell us how to think of such tricky problems.
I think that I am an average student but slowly reaching my there. What I used to do before I just used to look at problem and immediately decide whether I can or not but now I try to think more in depth and give sometime to the problem. and I would say it is totally fine to be wrong sometimes You just get to learn new things.
Can someone solve this for me? In the army of Andromeda, the soldiers are segregated by rank. Each soldier except the first has a superior officer.

The first officer who gets the information from two of his subordinates would detonate the nuke. Given m such queries find the officer who would detonate the nuke for each of them Input Format First line has an integer n,m, for the number of soldiers and number of queries. Second line has n−1 integers p2,p3,p4 … pn where pi is the superior officer of officer i. Next m lines have 2 integers a and b, such that the codes are given to soldiers a and b. Constraints 1
Hi sir , just a small information , if we take certification for python and pandas and if we try for a job will we get good job , actually having experience of 7 years and trying to switch career to be in good start if I did certification and try for job and luckily if we got in service based company , can it be a good start as part of career switch so that we will keep on working and try for big companies after we habituated with python work culture ?? Please replay sir with your views really need your help on this sir. Or suggest any certification which will help us to boost career

Far out I'm stuck in this bat and ball analogy and after reading explanations in comments I still couldn't figure it out. Does that mean I can't be (or shouldn't be) a programmer?
Hello sahil, Thanks for sharing this video. I believe this will help so many coders. Coding is not about memorizing it's all about building intuition and practice.
I just want people to understand, that to some people things WILL come more naturally than it will to others. And for a lot of people, no amount of hardwork will make you as good as the people to who it comes naturally. The faster you understand that and stop guilt tripping yourself, the better it will be for you and for your health. It doesn't make you worthless, it's just that you'll be useful in different roles than those people. And you can still do you part, but there might be somebody who'll be able to do the things you do faster, and in a way that you may never conceive. And you cannot learn that. The fast you realise that, the better it will be for you. Anybody that tells you that hardwork will make you as good as the person that it comes naturally to, is lying to you The only person you should compare yourself to is you. You can become better than you were. You can even be more productive than the genius. You can even produce better work than the genius, but you're not gonna be able to train yourself to become better at coming up with things that comes naturally to them.
The so called naturally gifted people just have the right framework which the hardworking people lack everyone is created equally but not everyone uses their full potential
@@hhandle no. Everyone is not created equal. Some people just have the innate ability to do certain things which others will have to work very hard to get to be able to do. And there's absolutely nothing you can do to change that.
I am solving problems on leetcode for 3 days , but i feel very struggling even on the easy questions i am able to think some of the approaches to solve a question but when it comes to code that solution i struggle a lot 😭 is it normal ? btw I'm learning dsa from 3 months I'm in my 3rd sem
Well, rather than directly jumping to coding by yourself, analyze different codes for different problems that are available on different platforms. Make sure that you try to analyze why they have done a particular line of code that way. Do this for at least 15-20 days, by this way you'll build your confidence and you know the tricks as you have analyzed different codes. Taking your time is the key! Hope it helps. All the best!
i have been coding since 5 months , almost done with dsa and solved around 106 problems on leetcode but still I cannot solve questions on my own , i have to refer the solution, is this normal?? or i m not very good at coding? i am a first year student
Hate to break it to you, but it's not, 5 months is a lot of time to solve just 106 problems. However if your are talking about 106 hard level leetcode problem, then it's awesome
I felt the same but I am improving. You will improve. Because I also thought I can never do exercises by myself. But now I am able to do some by my self. Just try and read the solutions to the codes and then familiarize yourself with the logic they used to solve those exercises.😊

The bat is $1 plus the cost of the ball. The total is the cost of the bat + the cost of the ball. So the total is $1 + the cost two balls. The cost of the ball is then ($1.10 -$1)/2.
@@nagrajsingh8437 buddy now I am more confused your solution doesn't work for me. And the question say a ball so i thought there will be 1 ball. Please correct me if I am wrong
The problem states that sum of bat price and ball price is $1.10. Also, cost of bat price is 1 dollar more than that of ball price. Find the ball price. Let ball price be x; Bat price = 1 + x; Bat price + ball price = $1.10 (given) //putting values (1 + x) + x = 1.10; 2x = 1.10 - 1 = 0.10; x = 0.10/2 = 0.05; Hence ball price is 5 cent. Hope you got it 😇
I think my brain is thinking super slow, I couldn't even understand the bat and ball thing 🤣
Same bro😂😂
Here the trick part is "the bat cost 1 dollar more than the ball"
Which means, the ball cost is also there in the bat plus 1 dollar.. so if the ball cost $0.10 then the bat would cost $1.10 and total would be $1.20 dollars which is not the right answer.

After watching this Video Who wants to learn DSA from Saahil 🙋🙋♀️?
To people like me :
Let the cost of the ball be "B" in dollars. According to the information given, the bat costs $1 more than the ball, so the cost of the bat would be "B + $1."
Now, we know that together, the bat and the ball cost $1.10. So, we can set up an equation:
B + (B + $1) = $1.10
Combining like terms:
2B + $1 = $1.10
Subtract $1 from both sides of the equation:
2B = $0.10
Now, divide by 2:
B = $0.10 / 2 = $0.05
So, the cost of the ball is $0.05 or 5 cents.
The thing about finding new patterns when you hit a wall is so true. I used to have trouble solving certain problems and then I found out about dictionaries and tuples. I was able to solve so many more after it. Need to find more patterns again. Thank you!
Let's say the cost of the ball is x.
Since the bat costs $1 more than the ball, the cost of the bat is x + $1.
The total cost of the bat and the ball together is $1.10, so we can set up the equation:
x + (x + $1) = $1.10
Combine like terms:
2x + $1 = $1.10
Subtract $1 from both sides:
2x = $0.10
Divide both sides by 2:
x = $0.05
So the ball costs $0.05, or 5 cents!
See I made it really simple...
Instead of bat and ball we use different question...
And also won't be using the word more than ($1 more than the ball) that stupid line causes all the confusion...
We will use extra instead of more ok..
So let's say u tell ur friend
Me : I got 20 rs extra from my uncle compared to aunty ...

The problem states that sum of bat price and ball price is $1.10. Also, cost of bat price is 1 dollar more than that of ball price. Find the ball price.
Let ball price be x;
Bat price = 1 + x;
Bat price + ball price = $1.10 (given)
//putting values
(1 + x) + x = 1.10;
2x = 1.10 - 1 = 0.10;
x = 0.10/2 = 0.05;
Hence ball price is 5 cent.
Hope you got it 😇
Still now my slow brain hasn't figured out the reason for that bat and ball questions 🥲
bat cost is more than $1 from ball ,that means ball cost + 1$ = bat cost. means 5 cent (ball) + 5 cent & 1 $ (bat) =1.10$
X = Bat and Y = Ball
x+y = 1.10
x-y = 1 it means x = 1+y
(1+y) + y = 1.10
1+2y = 1.10
2y = 1.10-1
y = 0.10/2
y = 0.5
Ball cost = 5 Cents
