Day 119/150 #150DaysOfCode | Sequence Tracking Mechanics
Cracked LeetCode 128 (Longest Consecutive Sequence) using Brute & Optimal approaches!
1️⃣Brute: Sorting | O(N log N) TC | O(1) Aux SC
2️⃣Optimal: Hash Set Sequence Start | O(N) TC | O(N) Aux SC

🚀 #Day 196/100 (Smallest Missing Integer Greater Than Sequential Prefix Sum @LeetCode)!
Key: Find longest sequential prefix, compute its sum, then find smallest missing integer ≥ sum.
⌛ O(n²) | O(n)
✅ Accepted

Day 98 of #100DaysOfCode 🚀
Solved LeetCode 3731: Find Missing Elements ✅
Used HashSet + traversal to find missing values in the range.
⏱ Time: O(n + range)
💾 Space: O(n)
Stored numbers, scanned range, and found missing values. 🔥
#LeetCode #DSA #Java #HashSet #Algorithms
🚀 #Day 183/100 (Split Array into Min Consecutive Subsets @GeeksforGeeks –#Daily)!
💡 Count E where x-1 is missing → each is a subset start. Hash Set = O(1) lookups.
✅ O(N) | O(N)
Consistency > Intensity. Keep pushing! 💪
