day 48 of #100DaysOfCode solved the #potd on leetcode 3147. Taking Maximum Energy From the Mystic Dungeon first use the brute force double loop O(n^2) after this apply the dp in this which state that dp[i]=dp[i+k]+energy[i]; and return the max in dp; #geeksforgeek #leetCode #DP

day 30 of 100 days of code solved gfg potd today question was too easy (reverse the queue) use the stack to store the front element and pop from queue and reverse the process second approach is to use the queue ; #100DaysOfCode #dsa #Geeksforgeek #LeetCode #Stack #Queue

day 28 of 100 days of code solved the decode the string use the stack to store the char of string and when encounter "]" pop the string and rev it and push it (after repeating it n times) again repeat this process time O(n) #100DaysOfCode #GeeksforGeek #dsa #Stack #LeetCode

🎊 Day 311 of @geeksforgeeks #POTD! Solved "Count unique vowel string" 🧩 🔹 Counted vowel occurrences 🔹 Calculated combinations by picking 1 per vowel 🔹 Multiplied by permutations of selected vowels 🎉 Thanks to @geeksforgeeks ! #GeeksforGeek #GeekStreak2025

🎊 Day 122 of #GFG160 ! Solved “Minimum Jumps” 🏃‍♂️ 🔹 Used bottom-up DP 🔹 Initialized last index with 0 🔹 For each index, checked reachable jumps 🔹 Updated `dp[i] = min(dp[i], dp[j]+1)` if path exists 🎉 Thanks to @geeksforgeeks ! #GeeksforGeek #GeekStreak2025

🎊 Day 121 of #GFG160 ✅ Solved Coin Change (Min Coins) using bottom-up DP with 1D array for optimal subproblem reuse. 💡 🎉 Thanks to @geeksforgeeks 🙌 #GeeksforGeek #GeekStreak2025

🎊 Day 307 of @geeksforgeeks #POTD ! completed! Solved Divisible by 13 🧮 🔹 Approach: Used modular arithmetic to build the number digit by digit and checked divisibility using `% 13` on the fly to avoid large number conversions. #GeeksforGeek #JavaScript

🎊 Day 118 of #GFG160 ! Solved Min Cost Climbing Stairs 🧗‍♀️ 🔹 Approach 1: DP with array to store min cost at each step 🔹 Approach 2: Space-optimized DP using two variables 🎉 Thanks to @geeksforgeeks ! #GeeksforGeek #GeekStreak2025

🎊 Day 115 of #GFG160 ! 🧩 Problem: Count Palindromic Substrings 🔍 Approach: Used center expansion to count all odd & even length palindromes. Checked around each index efficiently. 🎉 Thanks to @geeksforgeeks ! #GeeksforGeek #GeekStreak2025

🎊 Day 114 of #GFG160! 🧠 Problem: Longest Palindromic Substring 🔹 Expand around center (odd & even lengths) 🔹 Track longest valid palindrome using two pointers 🔹 Update max length & starting index dynamically 🎉 Thanks to @geeksforgeeks! #GeeksforGeek #GeekStreak2025

🎊 Day 112 of #GFG160 done! Solved Longest common Subsequence ! 🧠 Approach: Used DP to build a `lis [ ] array, updating each index based on previous increasing elements. 🎉 Thanks to @geeksforgeeks! #GeeksforGeek #GeekStreak2025

🎊 Day 301 of @geeksforgeeks #POTD! Solved Sum of Subarray Minimums Approach: Brute-force gave TLE, so optimized using monotonic stacks to find NSL & NSR, then calculated each element’s contribution. #GeeksforGeek #GeekStreak2025!
