题目描述

Two players play a simple game. Each player is provided with a box with balls. First player's box contains exactly n1n_{1} balls and second player's box contains exactly n2n_{2} balls. In one move first player can take from 1 to k1k_{1} balls from his box and throw them away. Similarly, the second player can take from 1 to k2k_{2} balls from his box in his move. Players alternate turns and the first player starts the game. The one who can't make a move loses. Your task is to determine who wins if both players play optimally.

输入格式

The first line contains four integers n1,n2,k1,k2n_{1},n_{2},k_{1},k_{2} . All numbers in the input are from 1 to 50.

This problem doesn't have subproblems. You will get 3 points for the correct submission.

说明/提示

Consider the first sample test. Each player has a box with 2 balls. The first player draws a single ball from his box in one move and the second player can either take 1 or 2 balls from his box in one move. No matter how the first player acts, the second player can always win if he plays wisely.
