LC Category Index (wisdompeak)

Interview MetaNicheredirect Updated Sep 18, 2026

Scope — A pointer to the wisdompeak problem taxonomy, and a map from its 29 categories to the cheatsheet in this repo that teaches each one. The taxonomy itself is not mirrored here. See also: lc_pattern.md — the curated pattern→problem map to study from; 00_template.md — the structure every sheet below follows.

The source

The taxonomy lives upstream and is maintained there:

wisdompeak/LeetCode — Readme.md — 29 categories, ~1,300 problems, each linking to a worked C++ solution.

This file used to be a verbatim copy of that README. A mirror of someone else’s index cannot be kept current, was never edited here, and taught nothing that the per-topic sheets do not teach better — so it is a link now. What follows is the part that is genuinely this repo’s: which of our sheets covers each of their categories.

Their category → our sheet

wisdompeak category	Start here	Then
Two Pointers	2_pointers.md	sliding_window.md, n_sum.md
Binary Search	binary_search.md	sort.md
Hash Map	hash_map.md	hashing.md, set.md

Design	design.md	design_examples.md, ood_design.md
Stack	stack.md	monotonic_stack.md, stack_expression_parsing.md
Deque	monotonic_queue.md	queue.md
DFS	dfs.md	dfs_advanced.md, backtrack.md
BFS	bfs.md	bfs_advanced.md
Trie	trie.md	string_matching_kmp_rolling_hash.md
Linked List	linked_list.md	2_pointers_linkedlist.md
Dynamic Programming	dp.md	dp_pattern.md, knapsack.md, kadane_algorithm.md
Bit Manipulation	bit_manipulation.md	dp_bitmask.md
Divide and Conquer	advanced_divide_and_conquer.md	sort.md

Greedy	greedy.md	intervals.md, scanning_line.md
Simulation	advanced_simulation.md	matrix.md
SQL	—	`leetcode_SQL/`

Four of their categories have no counterpart here and are best read upstream: Others, LeetCode Cup, Templates (their C++ snippets), and the per-problem solution folders each entry links to.
