bhaiya, i think the most important thing in this course is you are developing intuition and how to think or approach to a particular question along with how can we relate with things that we are already learnt. Amazing
1:03:33 There's one more approach to find power of 2. We find the quotient of the given number and if the modulus of the quotient is 0, then it is in power of 2 else false. int main(){ int n; coutn; cout
you will have to run it in a while loop actually, till the quotient is 0, because in this case, let n = 36, then p = 36/2 = 18 here 18%2 = 0 hence the output will be "power of 2" which will be false.

Hi Bhaiya, Just started your tutorial and learning DSA in a good way. Just wanted to mention to all that I have figured out one more way to reverse an array: for (int i = sizeOfArr; i > sizeOfArr / 2; i--) { int tempValue = arr[i - 1]; arr[i - 1] = arr[sizeOfArr - i]; arr[sizeOfArr - i] = tempValue; }

HW (20:36) - Two methods to initialize any no. of elements with any value in an array: - int array4[7]; fill(array4, array4 + 7, 3); int array5[7]; fill_n(array5, 7, 3);

Your C++ DSA video playlist is truly amazing! After searching all over RUclips for the best DSA content in C++, I finally found the perfect source. Thank you!
To initialize the whole array with a constant value other than 0 , We can use two methods in C++ method 1: using STL (preferred) fill(array, 100, 2); Will fill the whole array with a value of 2 method 2: using loop int array[100]; for (int i = 0; i < 100; ++i){ array[i] = 2; } Hope this helps
20:48 #include using namespace std; int main() { int a[100]; fill_n(a, 100, 1); //intializes an array named a of 100 size with value 1 for each element for (int i = 0; i < 100; i++) { cout
honestly i am really enjoying this course. Thank you for creating a free valuable course. And what you said on your latest video posted on 15th sept about the camera cover" free ki chiz acchi nhi hoti" but you are wrong. This free course is really a gem

Some knowledge about array - When we partly initialize array with any number other numbers get automatically initialized with 0. So , that's why , when we do this int arr[20] = { 0 } , this will initialize the arr[0] will 0 and as it is partly initialize .Therefore all rest of the element get initialize with zero .

I have another approach for Power of 2 as well. For odd and negative integer directly return false. For positive even integer just right shift them until 2 is obtained. If 2 is obtained it's a power of two, otherwise it isn't. bool isPowerOfTwo(int n) { bool ans = false; if (n > 1; } return ans; }

bhaiya, i think the most important thing in this course is you are developing intuition and how to think or approach to a particular question along with how can we relate with things that we are already learnt. Amazing
You are the best teacher anyone can have. With such a good vibe and energetic voice.
Thanks for always pushing us and keeping us motivated
1:03:33 There's one more approach to find power of 2.
We find the quotient of the given number and if the modulus of the quotient is 0, then it is in power of 2 else false.
int main(){
int n;
coutn;
cout
you will have to run it in a while loop actually, till the quotient is 0, because in this case,
let n = 36,
then p = 36/2 = 18
here 18%2 = 0
hence the output will be "power of 2" which will be false.
50:20
If the output is showing "INT_MAX is not declared in the scope"
than use #include
it will work
Thanks it worked but why he is able to use it without the header file?
@@sayarnilroy5999 bro its depends upon the compiler u r using , some compilers do include them but some dont .thats why

If you use {1} to initialize an array:
Only the first element of the array is set to 1.
All other elements are left uninitialized, meaning they might contain random values (garbage values).

Hi Bhaiya, Just started your tutorial and learning DSA in a good way.
Just wanted to mention to all that I have figured out one more way to reverse an array:
for (int i = sizeOfArr; i > sizeOfArr / 2; i--)
{
int tempValue = arr[i - 1];
arr[i - 1] = arr[sizeOfArr - i];
arr[sizeOfArr - i] = tempValue;
}
their is some problem for odd number , if size of array is 5 so i > 5/2 then i > 2 because of in integer 5/2 is not equial to 2.5 it's equial to 2
we can do
for(int i=0; i
@@poojabhati5080 the concept which u r doing comes under stl.. and the one hes doing it is using 3 variables
u shud use sizeof(arr)/sizeof(arr[0])....

totally satisfied with your course sir.
love from bihar.
To initialize the whole array with a constant value other than 0 ,
We can use two methods in C++
method 1: using STL (preferred)
fill(array, 100, 2);
Will fill the whole array with a value of 2
method 2: using loop
int array[100];
for (int i = 0; i < 100; ++i){
array[i] = 2;
}
Hope this helps
It can be also done by using simple looping and all index elements declare be one
Yeah you did correct 💯

Thanks for teaching this valuable course for free bhayya ❤
it's more worth than a paid course 💯

we can also use only i to swap values of array
for (int i = 0; i < size/2; i++)
{
swap(arr[i],arr[size-i-1]);

👏
Lecture 9 completed 💯😊
Bro me bhi ye course krne ki soch rha hu ky me kar skta hu please bataye
20:46 We can use a loop to assign the value to each element individually, which works across all languages.
we can initialize and print entire array with 1 like this-
int main(){
int arr[10];
int n =10;
for(int i=0 ; i
No one can match this perfection level in DSA course 🥇🔥❤️

Hey, Thank you so much for this beautiful course but I use python for programming. So, I am watching this and learning the concepts from you and applying the knowledge in python. I have been struggling to nail DSA but looking at your course gives me confidence that I can learn DSA. I aiming for MAANG companies. Can you please guide me what additional reading or courses or practice that I would need for that. Thank you again and keep up the good work. Really hope to hear from you.
I am learning a lot from this course thanks love from Pakistan
Really you are from pak?

Let me tell you one thing...I am a beginner in DSA but you can count me in your list of people who got selected after learning from this DSA series....thanks....waiting for next video
Krishna, where are you now? Aayush from iGate
Instead of finishing a web series or anime. I am gonna finish this series.
actually, this line motivates many people like me to watch DSA tutorial
Question 2: (1:02:52)
#include
using namespace std;
int main(){
int array[100];
int n;
coutarray[i];
}
cout
int a[7];
fill_n(a,7,-1);
This "fill_n()" used to filled array with any specific value
I have another approach for Power of 2 as well.
For odd and negative integer directly return false. For positive even integer just right shift them until 2 is obtained. If 2 is obtained it's a power of two, otherwise it isn't.
bool isPowerOfTwo(int n) {
bool ans = false;
if (n > 1;
}
return ans;
}
Cheeje itni crystal clear ho rhi h ki bahut emotional 😭 ho gye andar se
Thanku bhaiya ❤
1:03:00 hw que solution
CPP:
#include
using namespace std;
int getSum(int arr[], int size)
{
int sum = 0;
for(int i = 0; i< size ; i++){
sum = sum + arr[i];
}
return sum;
}
int main()
{
int array[10000],size;
coutsize;
for(int i = 0; i>array[i];
}
cout
bhai aapke samjhane ki skills god. love you bhai.. thanks for your efforts.
THE WAY HE SAYS "BAHUT EASY HAI" IT SEEMS EVERYTHING MAY BE TOO EASY IF WE SAY SO FOR EVERY PROBLEM FACE IN OUR LIVES.THANKS BHAIYA❤❤
Jitna achha se aap pdate ho sayd koi itna achha se pdate hai.❤❤❤🎉🎉🎉
Very helpful vedio for learning dsa in c++ from basic to advance
aaj jake malum chala, ki max() aur swap() function bhi hote hai. college wale pata ni kya kya karwate rehte hai. thanks a lot bhaiya
