📌 208. Implement Trie (Prefix Tree)
🧠 Intuition:
Store words as paths → shared prefixes = faster search
⏱️ TC: O(n)
💾 SC: O(N*M)
💡 Tries = backbone of autocomplete 🔥
Consistency builds skill.

🌳 Binary Tree BFS
Q1161: Maximum Level Sum
💡 Not every deeper level is stronger — measure level by level!
⚙️ BFS → compute sum per level → track max
⏱️ O(n) | 📦 O(n)
Consistency is the real algorithm. 💪

✅Q.199 Binary Tree Right Side View
💡 Intuition:
Right view = last node at each level
⚙️ Approach:
Use BFS (level order traversal) & pick last node of every level
⏱️ T: O(n)|📦S: O(n)

📌 Path Sum III (Binary Tree DFS)
🧠 Key Idea:
Start from EVERY node, not just root!
⚙️ DFS + recursive sum tracking
⏱️ O(N²) | 💾 O(H)
✨ Small insight: Problems get easier when you stop thinking linearly.

Q1g
💡 Track max value from root → node
If current ≥ max_so_far → good node
⚙️ DFS + state passing
⏱️ O(n) | 📦 O(h)
Small insight, big impact 💯

✅ Q1318: Minimum Flips to Make a OR b Equal to c
💡 Bit Manipulation
🧠 Idea: Solve bit by bit
c = 1 → need at least one 1
c = 0 → both must be 0
⚙️ Time: O(1) | Space: O(1)
Small steps daily = big results 📈

🚀 Day 26 #LeetCode75
🧠 1207. Unique Number of Occurrences
💡 Trick: Don’t check numbers → check their frequencies
⚙️ Approach:
HashMap → count
HashSet → check uniqueness
⏱️ O(n) time | O(n) space
Consistency > Motivation 💯

✅ Asteroid Collision (Stack)
💡 Intuition: Simulate collisions using stack (like resolving conflicts step by step)
⚙️ Approach:
Push positive asteroids
Resolve when negative appears
Compare sizes → destroy accordingly
⏱️ O(n) time | O(n) space
Day9 of #LeetCode75 🚀
Solved: Increasing Triplet Subsequence
🧠 Intuition: Track 2 smallest values while iterating
⚙️ If num > second > first → Triplet found ✅
⏱️ O(n) | 📦 O(1)
From O(n³) → O(n) 🤯
Small optimizations = BIG impact. Keep building 💪

1 / LeetCode 75
Solved 2 problems today
Kids With the Greatest Number of Candies
→ Key idea: compare against global max, not every kid
Merge Strings Alternately
→ Two pointers + safety checks
→ Important lesson: while controls loop, if ensures bounds safety
