1. Mastering DSA Patterns: Your Foundation for Success

These DSA patterns are your bread and butter for coding interviews:

Two Pointers: Efficient array/list traversal (e.g., cycle detection, pair finding).
Backtracking: Exploring solution spaces for combinatorial problems (e.g., permutations, Sudoku).
Dynamic Programming (DP): Optimizing solutions by breaking down problems into subproblems (e.g., Knapsack, Fibonacci).
Binary Search: Fast element location in sorted data (e.g., square root finding, searching in rotated arrays).
Binary Tree Traversal & Views: Navigating tree structures (in-order, pre-order, post-order, top/bottom view).
Graph Algorithms: Analyzing relationships (BFS, DFS, Dijkstra's).
Monotonic Stack: Next greater/smaller element problems.
Bit Manipulation: Low-level operations (power of two checks, counting set bits).
String Manipulation & Pattern Matching: Text processing (substring search, pattern matching).
BFS + DFS: Graph exploration techniques.
Sliding Window: Optimizing subarray/substring problems.
