Petya studies in a school and he adores Maths. His class has been studying arithmetic expressions. On the last class the teacher wrote three positive integers a, b, c on the blackboard. The task was to insert signs of operations '+' and '*', and probably brackets between the numbers so that the value of the resulting expression is as large as possible. Let's consider an example: assume that the teacher wrote numbers 1, 2 and 3 on the blackboard. Here are some ways of placing signs and brackets:
Note that you can insert operation signs only between a and b, and between b and c, that is, you cannot swap integers. For instance, in the given sample you cannot get expression (1+3)*2.
It's easy to see that the maximum value that you can obtain is 9.
Your task is: given a, b and c print the maximum value that you can get.
Input
The input contains three integers a, b and c, each on a single line (1?≤?a,?b,?c?≤?10).
Output
Print the maximum value of the expression that you can obtain.

大致题意：a, b, c三个数，在三个数中，插入“+” 和“*”运算符的任意两个组合，求能组成的表达式的值得最大值。（可以用括号）
解题思路：没啥说的，直接暴力，总共就6种组合。
