Arithmetic expressions

Evaluate 100 arithmetic expressions as fast as possible.

Input

One expression per line on STDIN. Each expression contains 50,000 int16 numbers with operators +, -, *, / (integer division) and parentheses (, ).

-19550 - ((-14208 / (13583 + -19215)) + (-16832 / 797 + (9060 / -23627)) + ((-6060) + 24953))
30835 - 3703 - (-20089 * -6261 + ((-28985 - 29627) + (-17828 - (22773 / -4014) * 1630)))

Output

Print the int64 result of each expression, one per line, to STDOUT.
