Here we will be discussing how to generate all permutations of a string using an STL function next_permutation() in C++.
To find the count of a total number of set bits in the binary representation of an integer in two ways: a simple while loop and by using a built-in library function in C++.
This C++ code takes the input array from the user and sort it using the merge sorting algorithm and gives the final array sorted in ascending order.
