Consistency has been the key, and the support from the community has been invaluable. Here's to the milestones achieved and the ones yet to come!​ Thank you @geeksforgeeks For this wonderful opportunity and rewards.

🎉 Day 300: Triple Century Unlocked! 🎉. Today marks 300 consecutive days of coding, learning, and growing—one problem at a time. From subarrays to graphs, from recursion to bit manipulation, this journey has been both challenging and rewarding.​. #geekstreak2025 #gfg160

Join millions who have switched to Grok.

Day 160: Unique Number II ⚡.Used bitwise counting to find the two non-repeating numbers in an array where every other number repeats twice. XOR magic never fails!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 159: Unique Number I 🔍.Solved the problem using XOR – all duplicate numbers cancel out, leaving the unique one. Simple yet powerful bit manipulation trick!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 158: Find Missing Number in Array using Bit Manipulation ⚡.Used XOR to find the missing number in O(n) time and O(1) space. Clean, fast, and smart — bit manipulation for the win!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 157: Find Only Repetitive Element from 1 to n-1 🧠.Solved it using XOR trick — elegant bit manipulation solution!.Loved how simple logic beats extra space or sorting. #geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 156: Maximum XOR of Two Numbers in an Array ⚡.Used Trie to store binary representations and efficiently find max XOR pairs. A great mix of bit manipulation + Trie magic!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 155: Implement Trie 🔤🌲.Built a Trie from scratch for efficient word storage and search. Super useful for prefix-based problems like autocomplete or dictionary checks!.One step closer to mastering strings. #geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 154: Minimum Weight Cycle 🔄📉. Tackled the tricky problem of finding the minimum weight cycle in a graph!.Combined Floyd-Warshall with edge checks to catch the lightest loop. Graph theory magic ✨.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 153: Floyd-Warshall Algorithm 🌐📊. Solved all-pairs shortest path using Floyd-Warshall. Dynamic programming with triple loops and matrix updates — clean and efficient!.No edge weight left unturned 😄.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 152: Bellman-Ford Algorithm 🔁📉. Solved shortest path for graphs with negative weights using Bellman-Ford. Handled negative cycles like a pro!.Another powerful algorithm added to the list 🚀.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 151: Alien Dictionary 👽📘. Solved the Alien Dictionary problem using topological sort on characters based on alien language order. Fascinating blend of graph + string logic!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Solved Today's POTD : Clone an Undirected Graph. #geekstreak2025 #gfg160 @geeksforgeeks

Day 150: Accounts Merge 🔗. Solved the Accounts Merge problem using Union-Find!.Grouped emails by users and merged common ones. Great practice for disjoint sets and string manipulation. #geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 149: Flood Fill Algorithm (DFS) 🎨. Today I implemented the classic Flood Fill using DFS!.Just like the paint bucket tool—fill connected areas with a new color starting from a given point. #geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 148: Dijkstra's Algorithm 🚦. Shortest paths, fastest routes!.Implemented Dijkstra using a min-heap to efficiently find the shortest path. Graphs can be tricky, but Dijkstra makes the journey smooth. #geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 147: Minimum Cost to Connect All Houses 🏠. Classic MST problem!.Used Kruskal's algorithm with Union-Find to connect all houses at the lowest cost. Feels good to optimize cities, one edge at a time!.#geekstreak2024 #gfg160 @geeksforgeeks #geekstreak2025

Day 146 : Articulation point- II. #geekstreak2024 #geekstreak2025 #gfg160 @geeksforgeeks

@geeksforgeeks Also I'm already get gfg bag. But unfortunately I lost my 200+ day streak yesterday ☹️. Can i eligible for Tshirt. Also my friend is a new coder he also missed his streak yesterday for gfg tshirt. could him continue. He get the tshirt?? . Waiting for your reply. 😊.

Hey @geeksforgeeks,.Could you kindly share the detailed description of the GFG160 challenge and what exactly qualifies for the GFG T-shirt reward?.I’ve been solving one problem daily from either the course problems or the POTD. Would really appreciate a response 🙏.
