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 on the right. For example, the binary watch below reads “9:22.”
Given an integer enabled, which represents the number of LEDs currently turned on, return all possible times that the watch could display. You may return the answer in any order.
