WebJul 24, 2015 · Let us call the set of all the outcomes as the permutation set, and each permutation outcome as the permutation number. Each permutation number consists of 4 digits, chosen from the ${a,b,c,d}$. Each permutation number in this set is mapped to a number between $0$ to $23$. WebC++ Algorithm next_permutation () function is used to reorder the elements in the range [first, last) into the next lexicographically greater permutation. A permutation is specified as each of several possible ways in which a set or number of things can be ordered or arranged. It is denoted as N! where N = number of elements in the range.
