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.
class Solution {
public:
void moveZeroes(vector<int>& nums) {
vector<int>result = nums;
nums.clear();
for(int i=0;i<result.size();++i)
{
if(result[i]!=0)
{
nums.push_back(result[i]);
}
}
for(int i=0;i<result.size();++i)
{
if(result[i]==0)
nums.push_back(0);
}
}
};
