283. 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:

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

Special thanks to @jianchao.li.fighter for adding this problem and creating all test cases.

其实可以考虑改一下传统的排序方法进行计算。我是基于冒泡排序进行了改进。
