A digital clock displays times in 12-hour format without leading zeros (e.g., 1:05 or 12:30). Between 12:00 PM and 11:59 PM, how many times will every digit on the display be identical?
1
For all displayed digits to be identical without leading zeros, every digit must be the same single digit. The only time on a standard 12-hour digital display where all shown digits match is 11:11 (four 1s). Times like 1:11 have three digits, but 1 is not equal to 1:11 as a single uniform block unless written as 01:11, which standard 12-hour clocks without leading zeros do not show.
