@AmanSharma_554 Congrats bro...

75/75 – DSA Challenge ✅ solved -"Valid Number" Leetcode(Hard) It’s done. 75 days of logic, frustration, growth & patience. This challenge taught me that discipline > motivation. Critical thinking isn’t built overnight — it’s earned problem by problem. #Discipline #code #journey

Where's the best way to store large amounts of media at one place for free .As Google offers only 15GB per account!!

Day 74/75: DSA Crunch Time! 2 days left! Revisiting Kadane’s, Prefix Sum, Two Pointers, Binary Search. Crushed _3Sum Closest_, _Bouquets with Adjacent Flowers_. Patterns > Problems! 💻📚 #DSA #CodingChallenge

@AlokDevJourney Thanks bruh😊

@jaykr31 Good going bro!! Keep grinding...

Day 73 of 75 Days DSA Challenge 💻 Solved Intersection of Two Arrays on LeetCode today. Slowly inching toward the finish line — every problem solved is one step closer to mastery. #DSA #LeetCode #CodingJourney #75DaysChallenge

Day 72/75 of my DSA Challenge 💻 Solved “Reverse Nodes in Pairs.” Got stuck linking swapped pairs, fixed it using a dummy node + prev pointer ✅ Sometimes your logic’s right—just needs a tweak. Debug, dry run, and enjoy the process! #DSA #Coding #ProblemSolving

🧠 Day 70–71 of my #75DaysDSAChallenge Solved 2 LeetCode problems today 💻 🔹 Money in the Leetcode Bank 🔹 3Sum Closest Every problem strengthens logic & consistency. Nearing the finish line 💪 #LeetCode #DSA #Coding #ProblemSolving #MCA #100DaysOfCode

Day 68/75 DSA Challenge Complete! - Solved LeetCode #12: Integer to Roman ✅ Used Greedy Approach: subtract largest Roman symbol repeatedly Also learned Positional Approach: split number into thousands, hundreds, tens, ones Complexity: O(1) time & space 1994 → MCMXCIV 💎

Day 14–29 of my #50DaysOfUpskillingChallenge: Networking deep-dive 🌐 Learned Internet basics, TCP/IP, HTTP, DNS, client-server & P2P, routers & switches, LAN/WAN/PAN, Bluetooth/Wi-Fi/SIM, TCP congestion, CDNs, VPNs. Foundation set for cloud! ☁️

Day 67/75 #DSAChallenge 🧩 Problem: Count subarrays with sum = goal (LeetCode 930) ✅ Brute-force: O(n²) → TLE ⚡ Optimized: Prefix sum + freq array → O(n) Key takeaway: Prefix sums + hashmap = 💡 for subarray sum problems! #LeetCode #DSA #Coding

Day 66/75 of #DSAChallenge ✅ Solved “Contains Duplicate II” on LeetCode: check if duplicates exist within k distance. Used unordered_map to track last occurrence → O(n) solution! #100DaysOfDSA #Coding #LeetCode #HashMap

@striver_79 Day 65/75 of #75DaysOfDSA 💻🔥 Solved “Maximum Points You Can Obtain from Cards” on #LeetCode Pick k cards from either end to maximize points. Trick? Find the min subarray sum of size (n−k) using a sliding window and subtract it from total 💡 10 days to go 💪 #DSA

🎆 Day 63 & 64/75 – #75DaysDSAChallenge Happy Diwali everyone! 🪔 Kept the streak alive! Solved 2 #LeetCode problems: 1️⃣ Next Greater Element I – find next greater in superset 🔍 2️⃣ Next Greater Element II – circular version using stack ♻️ Consistency > excuses 💪 #DSA #Diwali

Day 62/75 of my DSA Challenge 💪 Solved “Implement Queue using Two Stacks” on LeetCode today. Loved how it flips the logic of stacks to simulate a queue — great exercise in understanding LIFO vs FIFO! #DSA #LeetCode #75DaysChallenge #Coding #ProblemSolving
