Arrays: move zeros to the left Given an integer array, move all elements that are 0 to the left while maintaining the order of other elements in the array. The array has to be modified in-place.

Example:

Given - [1, 10, 20, 0, 59, 63, 0, 88, 0]

Result - [0, 0, 0, 1, 10, 20, 59, 63, 88]

Next Permutation (Leetcode, Medium - Hard) ***

https://leetcode.com/problems/next-permutation/

Implement next permutation, which rearranges numbers into the lexicographically next greater permutation of numbers.

If such an arrangement is not possible, it must rearrange it as the lowest possible order (i.e., sorted in ascending order).

The replacement must be in place and use only constant extra memory.
