I have participated in Educational Codeforces Round 92 Editorial and in the hacking phase I was trying to hack 88307545 solution. The input data I used was:

2
1 25
100 250

The code will output (on local PC and on online compiler):

12 24
25 5
25 5
25 5
25 5
125 250

I write the second test case to make codeforces think "the first line from the output is for the first test case and the others are for the second test case", but I got unsuccessful attempt. I didn't understand why this didn't work? Can someone explain to me?

Thanks in Advance!
