Problem Statement

We have N squares assigned the numbers 1,2,3,\ldots,N. Each square has an integer written on it, and the integer written on Square i is a_i.

How many squares i satisfy both of the following conditions?

The assigned number, i, is odd.

The written integer is odd.

Constraints

All values in input are integers.

1 \leq N, a_i \leq 100

Input

Input is given from Standard Input in the following format:

N
a_1 a_2 \cdots a_N

Output

Print the number of squares that satisfy both of the conditions.

Sample Input 1

5
1 3 4 5 7

Sample Output 1

2

Two squares, Square 1 and 5, satisfy both of the conditions.

For Square 2 and 4, the assigned numbers are not odd.

For Square 3, the written integer is not odd.

Sample Input 2

15
13 76 46 15 50 98 93 77 31 43 84 90 6 24 14

Sample Output 2

3

#include <iostream>
using namespace std;
int main()
{
	int count = 0 , k=1 ;
	int z ;
	cin >> z;
	int N[z];
	for (int i = 0; i < z; i++)
	{
		cin >> N[i];
		if (k% 2 != 0 && N[i] % 2 != 0)
		{
			count++;
			
		}
		k++;
	}
	cout <<k << endl;
