WebApr 7, 2024 · Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers. ... n -= 1 while index < n: nums[index], nums[n] = nums[n], nums[index] index += 1 n -= 1 This is the resulting code. It is clear that this code is O(n) since there are no nested loops. WebIn Algorithm LOOP 1, the while loop continues until vi is equal to n/2. Since vi is chosen uniformly at random from the set [1, 2, ..., n], the expected number of iterations of the while loop is n/2. On each iteration, the algorithm performs a constant amount of work, so the expected run time of LOOP 1 grows linearly with n.
