Hi, just want to point out that the XOR operation you did is wrong even if answer is right.. you can't put -/0 in end! It will change the value of binary number and in XOR if bit are same result is 0 not 1.. it should be as follows - 10 -> 1010 = 01010 20 -> 10100=10100 ------------------------------- 11110 XOR Logic is simple if bits are same result is 0. Anyways great series. 🤚
Thank you so much for your explanation sir. Easy to understand and easy to analyze also,even non-programmer also should understand easy way of your explanation sir.
Hey riya, Mostly you follow which playlist i have done java now im doing collection framework next what should i do follow within few days i have interview also i want to crack that interview??
i knew three ways of doing this program of swap two numbers i didnt know we can use exor and that single statement. But the logic was good, it works well but which has less time complexity is it logic 1 and logic two????
Hi Pawan, Thanks for all your videos on FAQ. I think expression in last logic is still evaluated from Left to Right e.g. 10+20-(20). If a=b is executed first then both variables a and b will have same value 20 and expression will result in (20+20-20). Thanks
Your explanation is wrong at 11:04 to 11:07 The correct is *if both bits are same it returns 0 otherwise it returns 1.* a = 10 = 01010 b = 20 = 10100 a = a^b = 01010 ^ 10100 = 11110 = 30 b = a^b = 11110 ^ 10100 = 01010 = 10 a = a^b = 11110 ^ 01010 = 10100 = 20 I like logic 4 & 5. I appreciate you...
can you explain this question please sir Secure Vault is a lock manufacturing company, they are not doing so great. Recent crime statistics show that this company's lock is behind most of the successful robberies. They are not making distinct keys for all locks. A lock with key number 10 can be opened with all the other 1,2,5 numbered keys. Cops asked you to write a program for finding similar keys so that people can be alerted and they can change their lock. Input format: the input contains the single integer n. input constraints: 1
hello sir how toi write this program this is my interview question from IBM ...........Write a function that takes in a non-empty array of distinct integers and an integer representing a target sum, The function should find all triplets in the array that sum up to the target sum and print all the triplets. The numbers in each triptlet should be ordered in ascending order, and the triplets themselves should be ordered in ascending order with respect to the numbers triplets. If no three number sum, the function should return an empty array. Input = [8,10,-2,49,14] Target sum : 57 Output: [[10,-2,49]]
11:11 u complete made us confused. You can not take a 0 at last .and 0+1 will give you 1 or vice versa in xor . Although the result is correct but u explained wrong.
Sir in last apprach a+b - (a=b) .. when we assigning the value of b to a then a variable will be updated in program then while coming to a+b is should be actually 20 + 20 naa🥲🥲..
For printing the multiple variables at a time in one statement, we have to concanate in between both variables so we can make a space also when printing these variables.
Hello sir... your teaching is amazing...I am struggling to write a code for a java program...can you please help me out WAP to read value to an array except multiple of three position.

I have one java programming question to solve I give Input as 5 And type random binary numbers as input 1 0 1 1 1 My output should convert that binary number to decimal number 23
Although I already met swapping values lots of times, It was interesting to watch other ways of this process, I’m impressed. Thanks for the video!
::learning new ways of swapping from your videos. lil correction, at 11:49 extra zero should be put on the left side , then result will come as 30.

Hi, just want to point out that the XOR operation you did is wrong even if answer is right.. you can't put -/0 in end! It will change the value of binary number and in XOR if bit are same result is 0 not 1..
it should be as follows -
10 -> 1010 = 01010
20 -> 10100=10100
-------------------------------
11110
XOR Logic is simple if bits are same result is 0.
Anyways great series. 🤚
U r absolutely right bro👍🏻
yes
i was held in confusion , u cleared it thanks.
It's very impressive series that i have seen. I don't have words to explain about this series. Thanks a lot❤
Welcome
Cool ...Swapping in one statement makes sense ))
Thank you so much for your explanation sir. Easy to understand and easy to analyze also,even non-programmer also should understand easy way of your explanation sir.

11:09 if both are equals it return 0 but you say return 1 in xor operation
Super sir... Keep doing more programs like this.. The main key in this video is explaining skills and different logics...thank you very much..
Welcome
15:50 if assignment operator operates from right to left then after (a=b) , the a+b= will be 40 right? why we have to take it as 10 again??
i too have the same doubt. may be when it is happening in the same line. it wont work like that.
Thanks for the easy explanation but the logic of calculating XOR is not Right. please make corrections.
Main soch raha tha ki 1^1=1
Kab se hone laga
1^1=0
Wah bhai wah kya soch he tumari😂
Hello sir your explaination is best, please create videos on pattern questions pleasseee🙃
Hi Pawan, Thanks for all your videos on FAQ. I think expression in last logic is still evaluated from Left to Right e.g. 10+20-(20). If a=b is executed first then both variables a and b will have same value 20 and expression will result in (20+20-20). Thanks
then should is be like b = (a+b)-(a=b);
U mean 30 carat 20 ???? Please ^ = carat
Your explanation is wrong at 11:04 to 11:07
The correct is *if both bits are same it returns 0 otherwise it returns 1.*
a = 10 = 01010
b = 20 = 10100
a = a^b = 01010 ^ 10100 = 11110 = 30
b = a^b = 11110 ^ 10100 = 01010 = 10
a = a^b = 11110 ^ 01010 = 10100 = 20
I like logic 4 & 5.

Hi, just wanted to check if this logic can be used to swap the numbers?

That's nuts. I would never ask such a stupid question in an interview.
You showed in the X-OR table 0 0 becomes 0 and 1 1 becomes 0 but in the explanation u told opposite.
The "dash" is at start and not at last. Sir's mistake.
Nice sir.. Please cover all programs related to string..
Single statement doesn't give the output sir

WAP to read value to an array except multiple of three position.
Where multiples of three position will have sum of previous two values

a[3] = 5
a[4] = 6
