  • [LeetCode]Move Zeroes

    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.

    迭代,删除0,最后补全就OK。

     2 public:
     3     void moveZeroes(vector<int>& nums) {
     4         if(nums.size()<=1) return;
     5         vector<int>::iterator iter;
     6         int count=0;
     7         for(iter=nums.begin();iter!=nums.end();iter++)
     8         {
     9             if(*iter==0)
    10             {
    11                 nums.erase(iter);
    12                 iter--;
    13                 count++;
    14             }
    15         }
    16         while(count--)
    17         {
    18             nums.push_back(0);
    19         }
    20         return;
    21     }
    22 };
