The figure above shows decimal numerals displayed in seven-segment display as well as the smallest and largest time stamps displayed in 12-hour digital clocks with seven-segment display. The digits from 0 to 9 are displayed with 6, 2, 5, 5, 4, 5, 6, 3, 7, and 6 segments respectively. There are a total of 20 segments used to display the time stamp below. What is the largest time stamp that can be displayed with 20 segments? Type the time stamp in the format of (H)H:MM, for example 1:23.
