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.
翻译:给定一个数组nums,写一个函数将所有的0移动到最后,同时保持非零元素的相对顺序。
例如,给定nums=[0,1,0,3,12],调用函数以后,nums变成[1,3,12,0,0]

public:
void moreZeros(vector<int>& nums)
{
int n=nums.size();
int count=0;
int num=0;
for(int i=0;i<n;i++)
{
if(nums[i]==0)
num++;
else
{
nums[i-num]=nums[i];
count++;
}
}
for(int i=count;i<n;i++)
nums[i]=0;
}
};
