Read the problem statement carefully. Here you are given one pair of integer per line and your task is to determine the maximum cycle length over the entire integer between and including i and j. But nowhere is stated that from i to j.  So the following input gives the same result: 

Input 
1 10 
10 1

Output 
1 10 20 
10 1 20

Oooooo..... , here you have to maintain another thing. You have to output the i and j as they appear in the input.
