Problem

You are given two integers $a$ and $b$ . Insert one of the operators +, -, or * between them so that the value of the resulting expression is as large as possible. If that largest value can be reached by more than one operator, print NIE instead.

Input

A single line contains two integers $a$ and $b$ ( $-10^4 \le a, b \le 10^4$ ).

Output

Print the expression that yields the largest value, in the form a<operator>b=result, on one line. Wrap a negative operand in parentheses (for example (-5)). Do not put the result in parentheses. If more than one operator produces the largest value, print NIE instead.
