plzz refer the following solution for better understanding of the logic and implementation .

// Solution as follows

#include <iostream>
using namespace std;

int main() {
    int t;
    cin>>t;
    
    while(t--){
        int x,y;
        cin>>x>>y;
        
        int a=x/10;
        int b=y/10;
        if(x%10==0){
            // the floor correction was incorrect for room numbers divisible by 10
            a=a-1;
        }
        if(y%10==0){
            b=b-1;
        }
        
        // abs is missing. b Chefina can be on a higher or lower floor
        cout<<abs(a-b)<<endl;
    }
}
