Given an array of N integers. Write a program that prints the even elements of an array (that is, those elements that are even numbers) that have odd indices (element numbering starts at 0).
Input
First given number N — the number of elements in the array (1<=N<=100). Then, space-separated N numbers — array elements. The array consists of integers, modulo not exceeding 100.
Output
It is necessary to display in one line, separated by a space, all even elements of the array that have odd indices.
