Random engine cppreference
WebbRearranges the elements in the range [first,last) randomly, using g as uniform random number generator. The function swaps the value of each element with that of some other randomly picked element. The function determines the element picked by calling g(). This function works with standard generators as those defined in .To shuffle the … WebbUniform random bit generators uniform_random_bit_generator (C++20) Engines and engine adaptors linear_congruential_engine (C++11) mersenne_twister_engine (C++11) …
