C++ STL (Standard Template Library) is an ANSI/ISO standard that has become an integral part of C++ distributions. STL can be grouped into 6 components: containers, generic algorithms, iterators, function objects, adaptors, and allocators.
Random_shuffle is one of the methods in generic algorithms component. To use this method, we must #include <algorithm> in the program. The method randomly put elements in a vector from [first, last). The method follows uniform distribution, i.e. the probability of each N element is 1/N [1]. The complexity of random_shuffle method is O(N) or linear. |
