working on matrix exponentiation to solve problems such as fast fibonacci

Learned digit DP! added more problems; currently working on: https://dmoj.ca/problem/btoi13p2

Learned string hashing! specifically rabin-karp string matching algorithm - comparing rolling hash values and combining it with binary search to improve the speed of my programs

Decided to try some adhoc problems! Found some very interesting string manipulation problems. I noticed that for most problems, there was a key insight and once you found that idea, you pretty much solved that problem! currently working on https://dmoj.ca/problem/ccc23s3

Transitioned to solving more graph theory problems! Found a very useful idea: unordered_map is faster than map at .find() and switching allowed my solution to pass! currently working on https://dmoj.ca/problem/ioi13p1io

Worked on more strings and adhoc problems. Learned how to solve searching for permutations of strings and added to the list of problems. Currently working on determining if a substring of a word is in a sequence (https://dmoj.ca/problem/ccc03s4). Let me know if you have any tips!
