Always trim first when parsing params. #171

Sometimes even a simple string param may have redundant spaces like sample 2 in BagAndCards (SRM 679). Always trim first when parsing params will fix this.

The incorrect BagAndCards.sample is given below. Note that there is a trailing space in sample 2.

I have debugged my solution for quite a while and found this bug in Greed during the contest...QQ
