Pororo the penguin is playing with numbers! He is given ~3~ integers: ~A~, ~B~, and ~C~. He can multiply or add the three numbers in any order, but he wants to get the largest possible result using all three numbers. For example, valid results are ~A \times (C + B)~, ~(C \times A) + B~, or ~A + B + C~. Help him figure out the largest possible result!

Constraints

~-100 \leq A, B, C \leq 100~

Input Specification

The first line contains ~3~ space-separated integers, ~A~, ~B~, and ~C~.

Output Specification
