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.

Example:

Input: [0,1,0,3,12] Output: [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.

不小心下标又一次越界了。。。

class Solution {  public:      void moveZeroes(vector<int>& nums) {          int n = nums.size();          int a=0,b=0;          for(b=0;b<n;b++){              while(b<(n-1)&nums[b]==0){                  b++;              }              nums[a++]=nums[b];          }          while(a<n){              nums[a++]=0;          }      }  };
