Bill 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.

Possible variants:
- **a+b\*c=v1**
- **a\*(b+c)=v2**
- **a\*b\*c=v3**
- **(a+b)\*c=v4**

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 **(a+c)\*b**.

Given an integers `a`, `b` and `c`. Return **maximum value of the expression** that you can obtain.

Find the maximum value of an expression formed by three integers using + and * operations.
