WebDec 19, 2024 · Fisher–Yates shuffle Algorithm works in O (n) time complexity. The assumption here is, we are given a function rand () that generates a random number in O (1) time. The idea is to start from the last element and swap it with a randomly selected element from the whole array (including the last). Now consider the array from 0 to n-2 (size ... WebMay 19, 2024 · The most classic C++ way to iterate over elements is using iterators. Remember that using vector::begin ( ) and vector::end ( ) allow accessing at pointers to the start and end of a vector respectively. Moreover, you can use vector::rbegin ( ) and vector:rend ( ) to get the reverse iterator pointing the last and the first element respectively.
