Arithmetic Evaluation
Evaluate a parenthesized expression of single-digit positive integers and the binary operators +, -, *.
The order of operations differs from the canonical one in that operations have no precedence; they are simply evaluated from left-to-right, with only parentheses affecting the order of evaluation.
Every intermediate step is guaranteed to have absolute value no greater than 1,000,000,000.
Input:
Input is an arithmetic expression of single-digit positive integers, the binary operators +,-, * and parentheses (). The arithmetic expression will be well-formed and will have no spaces.
Output:
The evaluated value of the arithmetic expression.
