Block Game

You are attending the International Construction by Preschoolers Contest. Unfortunately, you are too old to participate, but you still enjoy watching the competition.

In between rounds, you are walking around the contest area when you see a toddler, one of the contestants, playing with her blocks. Annoyed that she is having all the fun, you decide to challenge her to a game.

You set up two stacks of blocks of a certain height. Then,
you and the toddler take turns removing some number of blocks
from the stack which contains the largest number of blocks (if
both stacks have the same number of blocks, the current player
can choose either stack to remove blocks from). The number of
blocks removed must be a *positive multiple* of the
number of blocks in the smaller stack. For instance, if there
is a stack with $5$
blocks, and one with $23$
blocks, then the current player can remove $5$, $10$, $15$ or $20$ blocks from the stack of
$23$ blocks. The player
who empties one of the stacks wins the game.

You have graciously decided to take the first move, but then a worry strikes you – might this devious preschooler still be able to beat you?

One line with two integers $N$ and $M$, satisfying $1 \leq N, M\leq 10^{18}$, the initial sizes of the two stacks of blocks.

Output a single line containing a single word: the word
“`win`” if you are guaranteed to win if
you play correctly, and the word “`lose`” if your opponent can force you to
lose.
