LeetCode 416: Partition Equal Subset Sum

🚀 Day 163 of My LeetCode Journey 🚀 416. Partition Equal Subset Sum 🫧 We are given an array of integers and need to determine whether it can be split into two subsets with equal sum. ▪️ First, we calculate the total sum of the array. If the sum is odd, it cannot be divided into two equal parts, so return False. ▪️ If the sum is even, the problem becomes finding a subset whose sum equals total/2. ▪️ Treat this as a subset sum problem, where we check if we can form the target sum using the given numbers. ▪️ Our DP state is defined as (i, target), which represents whether we can form the target sum using elements from index. ▪️ At each index, we have two choices: either pick the element or not pick it. ▪️ If we pick the element, we reduce the target by nums[i]; if we skip it, the target remains the same. ▪️used memoization (dp[i][target]) to store results and avoid recomputing the same. ▪️ If successfully found a subset with a sum of total/ 2, it means the remaining elements automatically form the other subset with the same sum. #LeetCode #DynamicProgramming #Python #CodingJourney #Day163 🔥
