Open the Lock
Explore how to apply Tree Breadth-First Search to solve the Open the Lock problem. Learn to calculate the minimum moves to reach a target combination on a 4-wheel lock while avoiding blocked positions. This lesson helps you grasp cyclic wheel rotations, deadend constraints, and strategic traversal to find the shortest path efficiently.

Statement
You are given a lock with '0' through '9'.
The wheels can rotate freely and wrap around cyclically; turning
'9'forward leads to'0', and turning'0’backward leads to'9'.Each move consists of rotating one wheel by one position (either forward or backward). ...
