 * Description: Move Zeroes
 * <p>
 * Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.
 * <p>
 * Example:
 * <p>
 * Input: [0,1,0,3,12]
 * Output: [1,3,12,0,0]
 * Note:
 * <p>
 * You must do this in-place without making a copy of the array.
 * Minimize the total number of operations.
