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>::iterator it, end;
end = nums.end();
for (it = nums.begin(); it != end;)
{
if (*it == 0)
{
nums.erase(it);
nums.push_back(0);
--end;
continue;
}
++it;
}
}
};
