Learning Pointers in Programming Day 25

Day 70 of #100DaysOfCode 💻 Solved LeetCode 523 – Continuous Subarray Sum using an optimized Prefix Sum + HashMap approach. 💡 Key Insight: If two prefix sums have the same remainder when divided by k, the subarray between them is divisible by k. ⚡ Reduced time complexity from O(n²) → O(n) #leetcode #coding #dsa #cpp #programming #placements

Recursion isn't hard. The way it's taught is. Every tutorial starts with Fibonacci, the worst possible example. Start here instead: "A function that calls a smaller version of the same problem until there's nothing left to solve." That's it. That's recursion. Fibonacci is just showing off. #ComputerScience #Programming #DSA #CodingTips

🚀 Day 51 of #geekstreak60 Consistency is starting to feel powerful now 💪 Today’s Problem: Target Sum A classic dynamic programming problem that really tests your understanding of subset partitioning and optimization. 🔍 What I learned: How to convert a target sum problem into a subset sum problem Importance of edge case handling (like negative and odd cases) Optimization using 1D DP instead of 2D 💡 Key Insight: Instead of thinking in terms of '+' and '-', we can transform the problem into finding subsets with a specific sum this makes it much more efficient! ✅ Problem Solved 📸 Screenshot attached I'm 51 days in and not stopping anytime soon 🔥 #geekstreak60 #npci #geeksforgeeks #dsa #coding #programming #100DaysOfCode #developerjourney

Binary Tree Zigzag level order Traversal Approach: Do normal level order traversal Keep a boolean leftToRight ( initialize with true ) For each level: If leftToRight - push values normally (from left) Else - push in reverse order (from right) Flip direction after each level ( leftToRight = !leftToRight ) #DSA #programming #coding #problem
