Start by sorting the string and printing that as the first permutation. Now, find the next permutation as follows: Let i be the last index such that input [i] < input [i + 1]. If there is no such index, then we’re done.

WebJun 30, 2024 · We use the first and simplest concept we came up with “ Basic Permutation 1: Remove ” i.e. remove each element in turn and recursively generate the remaining permutations. The problem we faced in a naive implementation was we had to do two swaps in order to pick the next element to remove. WebJul 12, 2024 · Algorithm to print the permutations lexicographic-ally: Step 1. Sort the given string in non-decreasing order and print it. The first permutation is always the string sorted in non-decreasing order. Step 2. Start generating next higher permutation. Do it until next higher permutation is not possible.
