Fenwick Tree Please!

Can anyone please suggest me some really basic problems that are based on Fenwick tree keeping aside the problems involving range update (I am still struggling with that, any resources for that are appreciated as well)? Problems can be from SPOJ, Codechef, any where (maybe not)?
