Evaluate Arithmetic Expression

You are given an arithmetic expression that contains non-negative integers along with two operators: addition (+) and multiplication (*). In this expression, multiplication has a higher precedence than addition (i.e., multiplication is performed before addition). There are no parentheses in the expression.

Your task is to calculate and output the value of the expression following the standard operator precedence. For example, given the expression 2+3*4, the result is computed as 2 + (3*4) = 14.

Note: The input is provided through the standard input (stdin) and the output must be printed to the standard output (stdout).

inputFormat

The input consists of a single line containing a string expression which represents the arithmetic expression. The expression includes non-negative integers and the operators + and * without any spaces.

Example Input: 2+3*4

outputFormat

Output a single integer, which is the result of evaluating the expression under the precedence rule (multiplication before addition).

Example Output: 14

2+3*4

14
