WebA permutation of size n is an array of size n such that each integer from 1 to n occurs exactly once in this array. A suffix is several consecutive elements of an array that include the last element of the array. An inversion in an array a is a pair of indices ( i, j) such that i > j and a i < a j. Input Each test contains multiple test cases. WebGiven an array of integers nums, find the next permutation of nums. The replacement must be in place and use only constant extra memory. Example 1: Input: nums = [1,2,3] Output: [1,3,2] Example 2: Input: nums = [3,2,1] Output: [1,2,3] Example 3: Input: nums = [1,1,5] Output: [1,5,1] Constraints: 1 <= nums.length <= 100 0 <= nums [i] <= 100 Accepted science behind cloud seeding https://edgeexecutivecoaching.com
