Day 72 of #LeetCode75 – Non-overlapping Intervals (Greedy + Sorting) Sort by end time Count non-overlapping intervals Remove the rest Time:O(nlog n) Space:O(1) #LeetCode #100DaysOfCode #DSA #CPlusPlus #CodingJourney
Day 71 of #LeetCode75 Solved Problem 2235 – Add Two Integers. A simple one today Time Complexity:O(max (m,n)) Space Complexity: O(1) #LeetCode #DSA #100DaysOfCode #CodingJourney
Day 70 of #LeetCode75 Today’s problem was really tough for me — Evaluate Division. Tried multiple times, got stuck, got frustrated… But didn’t give up. I understood and solved it with the help of YouTube Not my cleanest day, but definitely a learning day. Progress is progress.
Day 69 of #LeetCode75 – Problem 790 (Domino & Tromino Tiling) Today learned the DP + recurrence relation approach. Interesting formula: T(n) = 2·T(n-1) + T(n-3) Slowly understanding these DP patterns. #DSA #DynamicProgramming #100DaysOfCode #CodingJourney
Day 68 of #LeetCode75 – Problem 649: Dota2 Senate Didn’t solve this one on my own today. I explored the queue-based solution to understand how the banning simulation works. Not my solution, but definitely my learning. #LeetCode #DSA #CodingJourney #100DaysOfCode #CPlusPlus
