LeetCode patterns + 3‑month roadmap

- Social posts mapped high‑value LeetCode problems to core patterns (e.g., Sliding Window: LC 3, 76, 424; Two Pointers: LC 11, 15, 167) and offered a disciplined three‑month interview plan. - The roadmap proposes Days 1–30 for foundations (two easy problems per day and CS basics), Days 31–60 for medium problems and system‑design mocks, and Days 61–90 for timed practice and application. - The advice stresses pattern muscle memory, steady daily practice, and pairing algorithm drills with systems/design prep for Big Tech interviews.
