Mathematics

Find which math expression matches the answer that you are given, if you have an integer answer, and a list of math expressions.

Task

Test each math expression to find the first one that matches the answer that you are given.

Input Format

Two inputs: an integer and a space separated string of math expressions. The following operations need to be supported: addition +, subtraction -, multiplication *, division /.
An expression can include multiple operations.

Output Format

A string that tells the index of the first math expression that matches. If there are no matches, output ‘none’.

Sample Input

15
(2+100) (5*3) (14+1)

Sample Output

index 1 

Explanation

Index counting starts at 0, so (5*3) is at index 1 and matches your answer of 15.
