DevNest on Instagram: "Backtracking is an algorithmic technique where we try a solution, check if it works, and undo (go back) if it fails — until the correct solution is found. Think of it as trial, error, rewind, repeat 🔁🧠 Used in problems like N-Queens, Sudoku, permutations, combinations, maze solving, and more. If brute force tries everything, 👉 Backtracking tries only what makes sense. 💡 Not used in shortest path algorithms. For shortest paths, we use Dijkstra, Bellman-Ford, Floyd-Warsh
