Timelimit: 1
Two friends ask the attendant a snack bar propose a challenge , so that whoever hit him more , would not pay the bill. Then the following is proposed : Given the following sum below report the result , with the same number of terms : S = 1 - 1 + 1 - 1 + 1 - 1 + 1 - 1 ... Write a program that , given a number of terms, report the result of the sum above.
Input
An integer C shall be informed , which is the amount of test cases. Each test case starts with an integer N ( 1 ≤ N ≤ 1000) , indicating the number of terms of the sum .
Output
For each test case print a number S , which is the sum of N terms of expression.

#1 Code Example with C++ Programming
Code -
C++ Programming
#include <iostream>
using namespace std;
int main()
{
int n , a;
cin >> n;
for(int i = 0; i < n ; i++){
cin >> a;
if(a%2 == 0){
cout << 0 << endl;
}
else
cout << 1 << endl;
}
return 0;
}

#2 Code Example with Javascript Programming
Code -
Javascript Programming
var input = require('fs').readFileSync('/dev/stdin', 'utf8');
var lines = input.split('\n');
const number = lines.shift();
let N = lines.shift();
let boolean = false;
let i = 0;
let S = 0;
while(i < number){
for(let j = 1; j <= N;j++){
if(boolean){
boolean = false;
S--
}
else{
S++
boolean = true;
}
}
boolean = false;
console.log(S);
S = 0;
N = lines.shift();
i++;
}
