The Bridge and Torch Problem is a classic puzzle in which four people need to cross a bridge at night using a single torch. Each person walks at a different speed, and when crossing, they must move at the pace of the slower individual. The challenge is to get all four across the bridge in the least amount of time, while adhering to the rules of torch sharing and limited crossing. To solve the problem, participants must strategize the order in which individuals cross the bridge, ensuring that the torch is always returned to the starting side. This requires careful planning and cooperation, making it a popular example in discussions about problem-solving and teamwork in mathematics and logic.
