{"@type": "Question", "name": "What are the most important LeetCode patterns for FAANG interviews?", "acceptedAnswer": {"@type": "Answer", "text": "The 10 patterns that cover ~80% of FAANG interview questions: two pointers, sliding window, binary search (on answer), BFS/DFS graph traversal, dynamic programming (knapsack and LCS variants), merge intervals, monotonic stack, heap/priority queue, topological sort, and trie. Master these patterns before grinding random problems."}},
{"@type": "Question", "name": "How do you recognize which pattern to use on a LeetCode problem?", "acceptedAnswer": {"@type": "Answer", "text": "Pattern recognition triggers: sorted array + find pair/triplet -> two pointers; substring/subarray optimization -> sliding window; find min/max in sorted space -> binary search on answer; connected components/shortest path -> BFS/DFS; overlapping subproblems -> DP; scheduling/meeting rooms -> merge intervals; next greater element -> monotonic stack."}},
{"@type": "Question", "name": "How many LeetCode problems should you solve?", "acceptedAnswer": {"@type": "Answer", "text": "100-150 problems solved deeply beats 400 problems solved shallowly. For each problem: solve it without hints first, study the optimal solution, understand why the pattern applies, and revisit it 1 week later. Spaced repetition on 100 key problems produces better results than once-through on 400."}},
{"@type": "Question", "name": "What is the blind 75 LeetCode list?", "acceptedAnswer": {"@type": "Answer", "text": "The Blind 75 is a curated list of 75 LeetCode problems covering the most common interview patterns, compiled from Blind.com posts. It covers: arrays, two pointers, sliding window, binary search, trees (BFS/DFS), dynamic programming, graphs, intervals, linked lists, and strings. It is the standard starting point for FAANG prep."}}
