Do I really have to ask two more questions? ? ?
T1: This question is too confusing
Correct answer: vector messing around? ? ? It seems to be some multi-dimensional difference, prefix and suffix sum.
T2: Tree of Life
Correct answer: Heuristic merging on trees. I just finished learning it, but there seems to be another way to merge tries.
T3: book pages
Correct answer: Rule, I just typed it out for the exam and didn’t delete the comments? ? ? Any more points? ? ?
T4: Endless questions, a happy cycle
Correct answer: KMP or Hash. I heard that Hash will be stuck? But I double hashed A, which was quite fast. Well, I made a fake hash.
