# Thread: Quiz of the day

1. ## Quiz of the day

Imagine the digital clock , how many times will the clock display three or more of the same number in a row over the course of one day?

In case you were wondering, the clock displays time on a 12-hour scale, not military time.

wrong

hint : it must be in a row, for example : 0111 or 1110 but not 1011.

If it is a 12 hour display, it should be 1200 instead of 0000, isn't it?

12. ## Re: Quiz of the day

then remove the 0000...
