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

For must know algorithms for data structures, I’d say:

Sorting (Quick/Merge/Heap),
Searching (Binary Search),
and Graph Traversal (BFS/DFS).

But the real MVP? Sliding Window and Two Pointers for array problems.

Resources? NeetCode.io breaks it down nicely.

And yeah, interview panic is real. Mock interviews help!
