🚀 LeetCode Daily Challenge – Day 4 (November 2025) 🧩 Problem: 3318. Find X-Sum of All K-Long Subarrays I 📚 Topic: Arrays | Sliding Window | HashMap | Prefix Sum 🔍 Approach: Used a sliding window of size k to compute the X-sum for each subarray. Maintained frequency counts of elements within the window and dynamically updated the sum as elements entered and left the window. This approach efficiently avoids recalculating sums from scratch for every subarray. ✅ Time Complexity: O(n) ✅ Space Complexity: O(k) 💡 Key Takeaway: Sliding window problems reinforce how optimizing repetitive computations can drastically improve performance — small logic, big impact! ⚡ #LeetCode #LeetcodeDailyChallenge #Coding #DSA #SlidingWindow #Array #HashMap #Day4 #Programming #Engineering
