Hello everybody!

Question

Please I don't know how to return -1 if result is not as expected or count if result is as expected.
If result is as expected I go through all tests but if not I don't know how to return -1.

Answer 1

What you mean?
You are returning it, in a way already.. How you want next?
Alternatively you can

if( m == count)
return count;

return -1;

// instead of your if else
