Given an array A of non-negative integers, half of the integers in A are
odd, and half of the integers are even.
Sort the array so that whenever A[i] is odd, i is odd; and whenever
A[i] is even, i is even.
You may return any answer array that satisfies this condition.
Example 1:
Input: [4,2,5,7] Output: [4,5,2,7] Explanation: [4,7,2,5], [2,5,4,7], [2,7,4,5] would also have been accepted.
Note:
2 <= A.length <= 20000A.length % 2 == 00 <= A[i] <= 1000
