Given an array A
of non-negative integers, return an array consisting of all the even elements of A
, followed by all the odd elements of A
.
You may return any answer array that satisfies this condition.
Example 1:
Input: [3,1,2,4] Output: [2,4,3,1] The outputs [4,2,3,1], [2,4,1,3], and [4,2,1,3] would also be accepted.
Note:
1 <= A.length <= 5000
0 <= A[i] <= 5000
A:
class Solution { public: vector<int> sortArrayByParity(vector<int>& A) { vector<int> res; for(int i =0;i<A.size(); i++){ if(A[i] % 2 == 0) res.push_back(A[i]); } for(int i = 0;i<A.size(); i++){ if(A[i] % 2 == 1) res.push_back(A[i]); } return res; } };
