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

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
int main(void){
  int n,t[100],m,p[100],x[100],i,time,j;
  time=0;
  scanf("%d",&n);
  for(i=0;i<n;i++){
    scanf("%d",&t[i]);
  }
  scanf("%d",&m);
  for(i=0;i<m;i++){
    scanf("%d",&p[i]);
    scanf("%d",&x[i]);
  }
  for(i=0;i<m;i++){
    for(j=0;j<n;j++){
      if(j==i) time+= p[j];
      else time+=t[j];
    }
    printf("%d",time);
  }
  return 0;
}
