As a cs student learning C++ and been doing some leetcode problems, this channel looks amazing!

[strokeadda]

Thanks for such an awesome playlist and amazing explanation so that we can refer whenever we stuck there...
Again thanks a lot!!

Your 250 videos totally solved with only java coding

Briallinat exaplenetion. Subscribed. Weting more questians.

[sahilrawat]

the way of coding is very different in leetcode as compare to C++ that we learn. how can we overcome with this?

Starting my Leetcode journey today. 22-09-24

[PIYUSH-lzzq]

Can you please make out a playlist for array only 🙏 this will helps bigginers !

[tyler]

This helped me pass time on the toilet. Thanks

[swamininarkhede]

how to set the normal c++ coding we learn
this c++ is not easy to understand

[ilyessouibgui]

can anyone solve this dsa problem...

Amy got a beautiful number K and she decided to play a game with this number. She iterated through each integer X from 1 to 10^18 and wrote down lcm(X, K)/X on a paper. Her score is the number of distinct even integers that she wrote down on the paper.
Find her score for the given K. Here lcm(A, B) denotes the least common multiple of A and B.
Constraints 1 <= K <= 10^12 All input values are integers.

Input Format :
First-line contains K, denoting the beautiful number.
Output Format :
Print a single integer denoting her score.

Sample Input :
2
Sample Output :
1

Explanation of Sample:
Here K = 2, lcm(X, 2) is either X or 2*X. Distinct integers that she would get are { 1, 2} out of which 2 is only even.
So, answer is 1.

What kind of hardware you use for the pen ? Please share the amazon link if you have of the pen and digital slate you are using.

Thanks for the playlist really need this😍

[krishnakhandelwalkk]

Is dsa required to solve these problems

[ghumakkad_yogi]

your way of explanation excellent I don't know why so less viewers

[sumitrawatofficial]

why this

?
we can also use
result.push_back(it);
result.push_back(p);
but this is showing error??but we can pushback iterator value in vector so why error is shown in my approach?

[swasthikadev]

How is the time complexity different??? Both have 1 for loop and find function. Someone pls reply

[manup]

What is time and space complexity of this program ? please tell for the second efficient approach.

[taeylerlyons]

What's the purpose of the "_map[num] = i;" at the very end?

[prathamsrivastava]

Thank you so much for making this whole playlist, especially in C++.
It helped me a lot.

also, Please continue making Leetcode solutions this this.
