Evaluate Mathematical Expression

You are given a string representing a mathematical expression containing non-negative integers and the operators +, -, and *. The expression does not contain any spaces. Your task is to evaluate the expression and print its result as an integer. The operator * has higher precedence than + and -. Use the standard order of operations!

The evaluation should follow the rules: \[ \text{Multiplication (*) has a higher precedence than Addition (+) and Subtraction (-)} \]

For example, the expression 3+5*2-6 is evaluated as 3 + (5*2) - 6 = 7.

inputFormat

The input consists of a single line containing the expression string.

For example: 3+5*2-6

outputFormat

Output a single integer representing the evaluated result of the expression.

For example, for the input above the output should be: 7

3+5*2-6
