For this I am using memorization by using . Check our Website: https://www. Palindrome Permutation II. The matrix Ais called irreducible if it is not reducible; see, e. A similar article for better understanding is here: … The general permutation can be thought of in two ways: who ends up seated in each chair, or which chair each person chooses to sit in. vector < vector < int >> subsets ( vector < int >& nums ); For example, for the input nums = [1,2,3] , your algorithm should output 8 subsets, including empty set and the set itself. Gather, I. It combines the inversion table representation of a permutation with factorial base representation of numbers. In the end, all the unique permutations are displayed on the console.
