WebMay 5, 2024 · • But if I apply this theory in this question then all permutations will be odd. I am confused here, is my solution incorrect? May be there will be more permutations with less elements like $(1,2,3) , (1,2,4)$? • Also there is a swapping logic! If the numbers are swapped odd times then it is odd and even otherwise WebA permutation of an array of integers is an arrangement of its members into a sequence or linear order.. For example, for arr = [1,2,3], the following are all the permutations of arr: [1,2,3], [1,3,2], [2, 1, 3], [2, 3, 1], [3,1,2], [3,2,1].; The next permutation of an array of integers is the next lexicographically greater permutation of its integer. . More formally, if all the …
