The program reads from standard input an arithmetic expression consisting of non-negative integers, the operators +, -, *, /, and (optionally) spaces. The expression contains no parentheses. The operator / denotes integer division (truncated toward zero), as in C/C++.
Print the value of the expression, computed following the usual precedence rules (* and / have higher precedence than + and -) and left-to-right associativity for operators of equal precedence.
The program reads from standard input a single line containing the expression. - The length of the expression is at most 200 characters. - Numbers in the expression are non-negative and have at most 9 digits. - The value of the expression and all intermediate sub-expressions fit in `long long`. - The operator `/` is integer division; the divisor is never zero.
The program prints to standard output a single integer: the value of the expression.
