…ality Templates: - No issues found (composer.py fix already applied) Solutions improved (LC 337, 124, 968): - Standardized block comment format per solution-contract - Semantic variable naming (rob_profit, skip_profit, global_max, etc.) - Pattern terminology alignment with templates.md See: docs/reviews/pattern-review-log.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Pattern Review Guide (pattern-review.md): - Add Section 6: Combined Pattern + Solutions Review Workflow - Document context-driven solutions audit process - Add dual-perspective quality criteria (pedagogical + engineering) - Include solutions audit checklist Solution Contract (solution-contract.md): - Emphasize concise block comments (3-4 bullet points max) - Add "What NOT to include" guidance - Add internal function comments section with examples - Include good/bad comparison table for comment quality 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Templates Review: - docs/patterns/string_dp/templates.md (1301 lines) - No issues found; comprehensive coverage of LCS, Edit Distance, Palindrome Subseq, Regex, and Wildcard matching Solutions Improved (semantic naming): - LC 1143: m,n,dp → len_1,len_2,lcs_length + type hints - LC 72: m,n,dp → source_len,target_len,edit_cost - LC 516: n,dp,t → string_len,reversed_s,lps_length - LC 10: m,n,dp → text_len,pattern_len,is_match LC 44 (Wildcard) used as reference standard - already had excellent naming (text_length, pattern_length, is_match). All tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
…ellent) Templates Review: - docs/patterns/string_matching/templates.md (977 lines) - No issues found; comprehensive KMP and Rabin-Karp coverage Solutions Audited (no changes needed): - LC 28 Find Index: Excellent naming (needle_length, failure, etc.) - LC 214 Shortest Palindrome: Excellent (palindrome_prefix_length) - LC 459 Repeated Substring: Excellent (period_length) - LC 1392 Longest Happy Prefix: Excellent (happy_prefix_length) All solutions already meet quality standard with semantic naming, type annotations, and concise block comments. Serves as reference for other patterns alongside LC 44 (Wildcard). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Templates Review: - docs/patterns/interval_dp/templates.md (711 lines) - No issues found; comprehensive coverage of 4 variants Solutions Improved (semantic naming): - LC 312: n,dp,k → balloon_count,max_coins,last_burst - LC 1039: n,dp,k → vertex_count,min_score,third_vertex - LC 1547: m,dp,k → cut_count,min_cost,last_cut - LC 664: n,dp,k → string_length,min_turns,match_pos All solutions received: - Standardized block comment format (3 bullet points) - Type annotations: list[list[int]] - Domain-specific naming (balloon, vertex, cut, character) All tests pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Game Theory DP Review findings: - Templates comprehensive (1156 lines) with 5 game patterns - All 3 existing solutions (LC 877, 486, 1406) already excellent - No improvements needed - solutions use semantic naming Solutions quality: All pass checklist (block comments, complexity, semantic names, type annotations, internal comments) Pattern status: Pending → Tier 2 (Silver) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Line Sweep Review findings: - Templates comprehensive (646 lines) with 5 quick reference templates - All 3 solutions (LC 253, 1094, 218) already excellent - No improvements needed - solutions provide multiple approaches each Solutions quality highlights: - LC 253: events, max_rooms, current_rooms (heap + sweep approaches) - LC 1094: passenger_change, pickup_location (diff array + events) - LC 218: current_max, active_heights (heap + SortedList) Pattern status: Pending → Tier 2 (Silver) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
