For a modern, effective, and zero-cost approach, consider this strategy:

Most coding interview questions are variations of roughly 15 to 20 foundational patterns. Once you learn to recognize the underlying pattern of a problem, you can map out a high-level solution before writing a single line of code. For example, instead of learning how to solve 50 different subarray problems, you learn the pattern once and apply it universally. Reduced Prep Time, Higher Retention

A pointer algorithm that uses two pointers moving at different speeds through a sequence. grokking+the+coding+interview+github+pdf+full

Perfect for detecting cycles in linked lists.

A pointer algorithm that uses two pointers moving through the data structure at different speeds (usually one step vs. two steps). For a modern, effective, and zero-cost approach, consider

Binary Tree Level Order Traversal, Zigzag Traversal. 8. Tree Depth-First Search (DFS)

Use GitHub repositories that focus on solutions to the patterns rather than searching for illegal full PDF leaks. The official site is constantly updated, whereas a PDF is static. Why Patterns Over Memorization? Reduced Prep Time, Higher Retention A pointer algorithm

By shifting your focus from "memorizing LeetCode 700" to "mastering 15 patterns," you will be much better equipped to handle unseen problems during your actual technical interview. To help you get started on the right foot, let me know:
