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

Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>

int main (void){

    int N,i;
    int x;
    char c;
    int count=0;


    scanf("%d",&N);
    scanf("%C",&c);

    for(i=1;i<=N;i++){

        scanf("%d",&x);
        scanf("%c",&c);

        //printf("block:%d get %d\n",i+1,x[i]);
        if(i%2==0){
            continue;
        }

        if(x%2==0){
            continue;
        }

        count++;

    }


    printf("%d",count);

    return 0 ;
