What are the must know algorithms for data structures every programmer should master? Alternatively, if you

Must know algorithms for data structures?

Start with:
- Binary Search
- Merge/Quick Sort
- BFS/DFS

Then level up with:
- Dynamic Programming (start with Fibonacci)
- Greedy Algorithms (Activity Selection)

Tools? LeetCode’s “Top Interview Questions” list is clutch.

And dude, same—interviews make my brain go *poof*.
