Guides on data structures, algorithms, and coding interviews to help you crack tech interviews.
Typical mistakes in coding interviews: off-by-one errors, wrong complexity, and how to avoid them.
High-frequency DSA questions reported in Amazon interviews: arrays, trees, graphs, and design.
A step-by-step roadmap for beginners: from basic syntax to arrays, then trees, graphs, and DP.
A day-by-day 30-day plan to cover arrays, trees, graphs, DP, and practice mock interviews.
The main DP patterns you need: 1D linear, 2D grid, knapsack, LCS, and state machine.
When greedy works, proof techniques, and classic problems: activity selection, intervals, and scheduling.
When to use a heap, top-K patterns, merge K sorted lists, and interview problems.
Classic stack and queue problems: valid parentheses, monotonic stack, BFS, and design problems.
Must-know linked list patterns: reversal, cycle detection, merging, and dummy nodes.
Essential binary tree and BST problems: traversals, LCA, validation, and recursive patterns.
Understand the difference between recursion and backtracking, when to use each, and common patterns in interview problems.
