Brain Game: Lighten Up
Here's a Tuesday Test Time to occupy a bit of your time. Enjoy!
We're all familiar with the the standard LCD/LED number displays as the one seen above (with seven segments that can be turned on and off to make up each digit). They've been used for years on watches, clocks, radios, and other devices that require numerical outputs. The example shown lights up 6 of the 7 available segments to display the number 9.
Suppose you had a one-digit display, like the one above, that counted from 0 to 9, then started over again and again. Now, suppose each segment of the display had a set limit of 10,000 light-up showings, and that any segment reaching that limit would immediately fail to light up. With this information in mind...
Which of the seven segments in the display
would be the LAST to still remain working
while the six others had already burned out?
