283.把数组中的0移到数组末尾 Move Zeroes

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.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

Note:

1. You must do this in-place without making a copy of the array.
2. Minimize the total number of operations.

public void MoveZeroes(int[] nums) {
	int length = nums.Length;
	for (int i = 0; i < length; i++) {
		for (int j = i; j < length; j++) {
			if (nums[i] == 0) {//如果等于0，则跟后面的元素交换
				int temp = nums[i];
				nums[i] = nums[j];
				nums[j] = temp;
			}
		}
	}
}
