In this method, we will use the rotate function of STL, which is used to rotate our string, and we are going to use recursion for printing the permutations. Example peavey 112 extension cabinet 40wWebAlgorithm using C++ STL We can generate all permutations of an array by making use of the STL function next_permutation. A call of next_permutation returns the next lexicographically smallest permutation. If the sequence is lexicographically largest, the function returns false.
