Evaluate Mathematical Expression

You are given a string representing a mathematical expression composed solely of non-negative integers, the plus sign + and the multiplication sign *. The evaluation must follow the standard operator precedence rules, i.e., multiplication is performed before addition. The numbers in the expression can have multiple digits.

For example, the expression 3+2*2 evaluates to 7 because the multiplication is executed first: \(3 + (2 \times 2) = 7\).

Your task is to compute the result of the given expression.

Input Format: A single line containing the expression.

Output Format: A single integer representing the evaluated result.

inputFormat

The input consists of a single line containing a string expression which includes digits (0-9), the addition operator +, and the multiplication operator *.

It is guaranteed that the expression is valid and does not contain any spaces or other characters.

outputFormat

Output a single integer which is the result of evaluating the expression according to standard operator precedence. In particular, the multiplication operation is performed before the addition.

3+2*2

7
