L29 - Multi Dimensional DP | Knight Dialer | 3D DP | LeetCode 935 | Memoization | Tabulation

Today in Lecture 29 of Multi Dimensional DP (GRID DP), we solve LeetCode 935 (MEDIUM). Knight Dialer problem using 3D Dynamic Programming. We'll be mapping knight movements into matrix and do valid digit transitions, tracking sequence length growth, and counting all possible phone numbers of length n which could be built through carefully layered DP states built from movement constraints and combinatorial reasoning, and along with 𝗪𝗘 𝗪𝗜𝗟𝗟 𝗕𝗘 𝗗𝗜𝗦𝗖𝗨𝗦𝗦𝗜𝗡𝗚 𝗟𝗢𝗢𝗣𝗦 𝗪𝗜𝗧𝗛 𝗥𝗘𝗖𝗨𝗥𝗦𝗜𝗢𝗡. Learn Recursion ⮕ Memoization ⮕ Tabulation ⮕ Space Optimization and build your DP foundation in Hindi.
