当人们看到一组数字时，通常会好奇它们之间是否存在某种关系？如果只有三个数字，这个问题就更容易处理了。

给定三个不同的正整数，你需要确定其中一个数是否可以通过另外两个数计算得出。如果这三个数中任意一个数是另外两个数的和，则输出 1；如果任意一个数是另外两个数的积，则输出 2；否则输出 3。假设这三种情况中恰好有一种成立。

输入仅有一行，包含三个不同的正整数，每个数都在 2 到 1000 之间（含 2 和 1000）。

输出上述对应的数字。

样例

输入格式 1

10 30 20

输出格式 1

输入格式 2

10 20 200

输出格式 2

输入格式 3

100 5 700

输出格式 3
