These are both pretty classical problems. But the way you've presented 
them sounds a bit like a "do my homework for me" style question.

Do you know any python? I recommend that you consider following a book 
or tutorial to get through some of the basics. I like to recommend Think 
Python (available for free from the author).

If you have particular questions that come up while you're trying to 
write a solution, I think more people would be more inclined to help.

Good luck! - DLD
