🎯 Linked List Loop FOUND — Not Just Detected! 🔁🔍
Day 72 of geekstreak2025 & the challenge just got deeper! 💻
Yesterday: “Is there a loop?”
Today: “Where EXACTLY does it start?” 🔥
🔧 Using Floyd’s Cycle Detection Algorithm + a pointer reset trick:
👉 Step 1: Detect the meeting point inside the loop
👉 Step 2: Reset one pointer to head
👉 Step 3: Walk both one step — meet at loop's entry! 🚶♂️🚶♂️
📈 This trick is used in real-time systems to detect cycles in memory, processes, and even dependency graphs!
