Problem of the Day
A new programming or logic puzzle every Mon-Fri

5/5

The fifth of May, what a glorious day. Today's problem is all about finding duplicates such as with today's date. For the numbers [10-10,000] print out all the numbers who only use one type of digit (ie: 55 but not 45). Can you come up with a sub linear algorithm to solve this?

    samelist = []
i = 1
while i < 9:
    number = i
    while number < 10000:
        samelist.append(number)
        number = i + number*10
    i = i + 1

print samelist

    Oops, that should be i < 10.
