L16 - 1D DP | Decode Ways | Intuition Building | LeetCode 91 | Recursion | Memoization | Tabulation
Today in Lecture 16, we solve LeetCode 91 (MEDIUM). Decode Ways problem using 1D Dynamic Programming with a focus on intuition building. The digit and pair-validity checks reveal how each position depends on one or two previous states, forming the recurrence that counts all meaningful decoding paths. Learn Recursion ⮕ Memoization ⮕ Tabulation ⮕ Space Optimization and build your DP foundation in Hindi.
