Description
You are playing a fast-paced number card game at a lively tavern. You draw two numbered cards, a and b. Each card contains an integer from 1 to 100. To win the pot, your hand must be considered lucky.
The dealer will declare your hand lucky if it satisfies either of these two rules:
- The sum of the two cards a and b is a multiple of 10, and the first card is larger than the second.
- The product of the two cards is less than 100, and the first card is greater than the second by more than 5.
Given the values of your two cards, write a program to determine if you have a winning hand.
Input
Two positive integers, a and b, provided on separate lines.
1 <= a, b <= 100
Output
If your hand satisfies at least one of the dealer's rules, print "Lucky!".
If you lose the round, print "Unlucky!".
