Hello Aspirant,
Hope you are doing well.
At the ZIO, participants are not expected to know any standard algorithms. It is more of a test of the participant's ability to think and solve problems. Hence generally, problems are of an ad-hoc nature. So doing any particular topics is probably not going to help much. However, if you practice solving programming contest problems, it would be easier for you to think fast and think correct during the ZIO. So I would suggest you to try coming up with algorithmic solutions for Div 2 problems on Topcoder/Codeforces.
However try for these topics:
2. <Algorithms>
Hope you got the answer to your question. Incase of any queries, feel free to question. Have a great day!
