[Leetcode] Move Zeros
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.
1. 首先想到的肯定是冒泡排序类似的算法。
2. 如果不用in-place的话,可以重新新建一个array,那所有的东西都很简单了。 ---> 看了答案。。。不用新建一个array, 直接用一个pointer来做就好
3. 还可以用Two Pointers来做。
