KMP and Trie
good luck!
Although you have to take some precaution against getting hacked on codeforces, I don't think there's a more versatile string algorithm than the polynomial rolling hash. It's a relatively simple algorithm that allows you to carry over your knowledge of prefix sums (which everyone should already have quite a lot of experience with) and apply them to string problems.
