next highest permutation leetcode
The next permutation is always greater or equal to the current permutation (we assume the numbers in the current permutation are not sorted in descending order). If such arrangement is not possible, it must rearrange it as the lowest possible order (ie, sorted in ascending order). If such an arrangement is not possible, it must rearrange it as the lowest possible order (i.e., sorted in ascending order). 3,2,1 → 1,2,3 My notes on leetcode Wednesday, October 22, 2014.
