How do you prepare for a section dedicated to algorithms and data structures?

To prepare for the algorithms and data structures section, I use the following approach:

1. Studying theory — I review the main structures (lists, trees, graphs, hash tables) and algorithms (sorting, searching, traversals).
2. Solving problems on platforms — LeetCode, Codeforces, HackerRank for practice and reinforcement.
3. Analyzing solutions — I analyze others' solutions to understand different approaches and optimizations.
4. Reviewing and systematizing — I keep notes and diagrams to quickly refresh my knowledge before the interview.

This systematic approach helps not only to memorize but also to learn how to apply algorithms effectively.
