LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - LeetCode 1466 – Reorder Routes to City 0 | C++ Graph DFS

In this video we solve LeetCode 1466: “Reorder Routes to Make All Paths Lead to the City Zero” using C++ and a clean graph + DFS approach. You will see: • How to model the directed roads as an undirected graph with edge directions stored separately • The key “trick” that tells us when we need to reverse a road • A step–by–step DFS traversal that counts the minimum number of edges to reorder • Full C++ implementation, line by line • Time and space complexity analysis This problem is a classic graph/DFS interview question and a great exercise if you’re preparing for FAANG-style coding interviews or improving your problem solving on LeetCode. 🔗 Problem link: https://leetcode.com/problems/reorder-routes-to-make-all-paths-lead-to-the-city-zero/ 📚 Watch the full LeetCode 75 playlist (C++ explanations + animations): https://www.youtube.com/playlist?list=PLF0G-7pZcOza_jyAxwMpa5KnK3vST5smK 💻 Technologies used • Language: C++ • Topic: Graphs, DFS, tree traversal, edge directions • Difficulty: Medium (but very common in interviews) ––––– If this helped you, consider: 👍 Liking the video 📝 Leaving a comment with the next LeetCode problem you want to see ✅ Subscribing for more C++ + algorithms explanations #leetcode #leetcode1466 #cpp #programming #graph #dfs #codinginterview
