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

Honestly, the must know algorithms for data structures list starts with the classics: Binary Search, Sorting (Merge, Quick), and Hash Tables.

But don’t sleep on Graph Algos—BFS/DFS are *everywhere*, and Dijkstra’s/A* for pathfinding.

Dynamic Programming? Knapsack, Fibonacci, and Longest Common Subsequence will save you in interviews.

For practice, LeetCode and GeeksforGeeks are gold.

And yeah, I totally blank in interviews too. Muscle memory helps—grind ‘em till they’re boring!
