🔥 Problem of the Day: Equal Row and Column Pairs Approach: Language: C++ Difficulty: Medium ✅ Passed all testcases #DSA #LeetCode75
Day 73 of #LeetCode75 452. Minimum Number of Arrows to Burst Balloons Key idea: Shoot one arrow for all overlapping intervals by minimizing the end range. Time: O(n log n) Space: O(1) #Day73 #LeetCode #DSA #GreedyAlgorithm #Intervals #CPlusPlus #CodingJourney #100DaysOfCode
Day 56 of #LeetCode75 — Problem 208: Implement Trie (Prefix Tree) Today I implemented a Trie — a tree-based data structure used for fast word insertions, searches & prefix lookups. Key concepts: Node structure with 26 child pointers Recursion for insert/search Dictionary
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 58 of #LeetCode75 Worked on Rotting Oranges (BFS) today. I wrote most of the solution myself (~60%), but needed some guidance to fix the BFS logic and boundary handling. #100DaysOfCode #LeetCode #DSA #codingjourney
Day 52 of #LeetCode75 — Problem 547: Number of Provinces Converted the adjacency matrix into an adjacency list and used DFS to count connected components. Each DFS run = one province. TC: O(n²) SC: O(n) #Day52 #LeetCode #DSA #CPP #CodingJourney
Day 54 of #LeetCode75 — Problem2336: Smallest Number in Infinite Set This one was tricky, learned it with help and understood the logic behind maintaining: A pointer (cur) to the next smallest number A min-heap to store numbers that were added back #Day54 #LeetCode #DSA #CPP
Binary Tree - DFS Maximum Depth of Binary Tree #LeetCode75 33/75 #Python #DSA #100DaysOfCode #LeetCode
🚀 Day 1 of my LeetCode 75 Challenge begins today! Just solved the first problem — #1768: Merge Strings Alternately ✅ One step closer to sharpening my DSA skills 💪 Consistency > Motivation. Let’s keep going! 🔥 #LeetCode #LeetCode75 #CodingJourney #100DaysOfCode

Day 75 of #LeetCode75 Solved 739. Daily Temperatures Using a Monotonic Stack Track index of temperatures in a stack. Whenever we find a warmer day → pop & compute the wait time. Time:O(n) Space:O(n) #Day75 #LeetCode #DSA #Stack #MonotonicStack #CPlusPlus #CodingJourney
“Today’s LeetCode Blind 75: Container With Most Water. Funny how the whole problem collapses once you realize one thing: Move. The. Shorter. Side. Most of y’all fighting O(n²) demons while I’m out here cruising with two pointers.” #Leetcode #leetcode75
Day 60 of LeetCode 75 Solved 1137. N-th Tribonacci Number 🔢 Practiced: • Recurrence → DP • Clean base cases • Space-optimized tabulation (3 variables) Simple problem, but great for building DP intuition. #LeetCode75 #Day60 #DSA #DynamicProgramming #100DaysOfCode #cpp
