Could you provide an example in your problem statement? Also, as Evan says below, you should have more than one test case or it becomes a trivial matter to hard-code a particular answer.
Probably should add a couple more test cases so that silly people like me don't submit answers like this. ;)
Remove all the words that end with "ain"
Extract leading non-zero digit
Specific Element Count
Find nth maximum
Calories in a slice of pizza?
How to add?
area of an annulus
