L2 - Subarrays DP | Maximum Subarray Sum | 2D DP | Bottom Up 3 Ways | LeetCode 53 Intuition
Today in Lecture 2 of Subarrays DP, we solve LeetCode 53 (MEDIUM). Maximum Subarray Sum problem using 2D Dynamic Programming. We'll be modeling subarray continuation choices, building clear DP states, and progressively simplifying the recurrence to reach an optimal solution while preserving the core intuition behind subarray formation. So, overall we will be discussing 𝟯 𝗗𝗜𝗙𝗙𝗘𝗥𝗘𝗡𝗧 𝗕𝗢𝗧𝗧𝗢𝗠-𝗨𝗣 𝗔𝗣𝗣𝗥𝗢𝗔𝗖𝗛𝗘𝗦 to understand optimization [ 𝗜𝗡𝗖𝗟𝗨𝗗𝗘𝗦 𝗢(𝟭) 𝗦𝗣𝗔𝗖𝗘 𝗢𝗣𝗧𝗜𝗠𝗜𝗭𝗔𝗧𝗜𝗢𝗡 𝗔𝗣𝗣𝗥𝗢𝗔𝗖𝗛 ] choices clearly. Learn Recursion ⮕ Memoization ⮕ Tabulation ⮕ Space Optimization and build your DP foundation in Hindi.
