Solution

import java.util.*;

class TestClass {

    public static void main(String args[] ) throws Exception {

        int i, n;

        Scanner s = new Scanner(System.in);

        n = s.nextInt();

        int sh[] = new int[n];

        int sm[] = new int[n];

        int eh[] = new int[n];

        int em[] = new int[n];

        int h[] = new int[n];

        int m[] = new int[n];

        for(i=0; i<n; i++)

        {

            sh[i] = s.nextInt();

            sm[i] = s.nextInt();

            eh[i] = s.nextInt();

            em[i] = s.nextInt();

        }

        for(i=0; i<n; i++)

        {

            h[i] = eh[i] - sh[i];

            m[i] = em[i] - sm[i];

            if(m[i] < 0)

            {

                h[i]--;

                m[i] = 60 + em[i] - sm[i];

            }

            System.out.println(h[i] + " " + m[i] + "\n");

        }

        

    }
