Binary Watch
Explore the binary watch problem where LEDs represent hours and minutes, and learn to generate all valid times given a number of LEDs turned on. Understand the rules for valid hour and minute formats, and apply backtracking methods to build a solution. This lesson helps you grasp problem constraints and develop a coding approach for similar combinatorial problems.

A binary watch has 4 LEDs for displaying hours (ranging from 0 to 11) and 6 for displaying minutes (ranging from 0 to 59). Each LED can be on (1) or off (0), with the least significant bit ...
