My issue

My code

# cook your dish here
T=int(input())
for i in range(T):
    A=input()
    X=int(A[0])
    Y=int(A[2])
    print(X-Y)

Try changing A[2]to A[1] and index of array start as 0,1,2…

I used C++ language.
Hope it helps, Thank you.

#include

using namespace std;

int main()
{
int T;

cin>> T; //number of test case
int b[T][2];
for(int j=0; j<T; j++)
 {for(int i=0; i<2; i++)
   {cin>>b[j][i];
   }
 }
 for(int j=0; j<T; j++)
  {int a = b[j][0]- b[j][1] ;
    cout<<a<<endl;}

 return 0;
