A binary watch has 4 LEDs on the top to represent the hours (0-11), and 6 LEDs on the bottom to represent the minutes (0-59). Each LED represents a zero or one, with the least significant bit on the right.
For example, if 3 LEDs are on showing binary values 100 for hours and 110011 for minutes, the watch reads "4:51".
Given an integer turnedOn which represents the number of LEDs that are currently on, return all possible times the watch could represent. You may return the answer in any order.
The hour must not contain a leading zero.
"01:00" is not valid. It should be "1:00".The minute must consist of two digits and may contain a leading zero.
"10:2" is not valid. It should be "10:02".0 <= turnedOn <= 10turnedOn = 1["0:01","0:02","0:04","0:08","0:16","0:32","1:00","2:00","4:00","8:00"]turnedOn = 9[]
