Problem Statement

Joisino wants to evaluate the formula "A op B".
Here, A and B are integers, and the binary operator op is either + or -.
Your task is to evaluate the formula instead of her.

Constraints

1≦A,B≦10^9

op is either + or -.

Input

The input is given from Standard Input in the following format:

A op B

Output

Evaluate the formula and print the result.

Sample Input 1

1 + 2

Sample Output 1

3

Since 1 + 2 = 3, the output should be 3.

Sample Input 2

5 - 7

Sample Output 2

-2

#include <iostream>
using namespace std;
 
int main() {
    int N, i, M, j;
    int sumT = 0;

    cin >> N;
    int T[N];
  
    for (i = 0; i < N; ++i){
      cin >> T[i];
      sumT += T[i];
    }

    cin >> M;
    int P[M], Q[M];
    for (j = 0; j < M; ++j){
      cin >> Q[j] >> P[j];
      cout << sumT - T[j] + P[j] << endl;
    }

}
