use size_t instead of int in your for-loops to get rid of the warnings in Sololearn.

You might have been using a compiler that allows comparison between int and size_t, but more strict compilers will raise a warning because you are comparing different types.

Answer 2

i don't get it, what should i input first ?

Answer 3

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
