Statement
Given a string, exp, represents an arithmetic expression in a
exp and return the resulting integer value.
The rules are given below:
The valid operators are
'+','-','*', and'/'.Each operand may be an integer or another expression.
The division between two integers always truncates toward zero.
There will not be any division by zero. ...
