September 2018 - Challenge

<< August October >>


This month, we revisit the GDPR subject we mentioned in the December 2016 challenge.

Once again, we'd like to chose a mono-gender group, this time of only three persons.

We have 26 people, whose names start with letters A to Z (Alex, Bailey, Chris, ...) and if we choose three with the same gender - we win. If not - we pay a GDPR fine and try again.

To make it more interesting, the only teams you are allowed to test are those whose initials form a word found in the dictionary with three different letters.

Find the shortest list (hint: less than 10 words) of three-letter words that ensure you'd get a mono-gender team.



As an example, if you want to do this for teams of two, the following five words will work: (OF,RF,IR,IN,NO).

Note that there is a shorter solution for the example challenge.



A bonus '*' will be given for more solutions in other (non-English) languages.




We will post the names of those who submit a correct, original solution! If you don't want your name posted then please include such a statement in your submission!

We invite visitors to our website to submit an elegant solution. Send your submission to the ponder@il.ibm.com.

If you have any problems you think we might enjoy, please send them in. All replies should be sent to: ponder@il.ibm.com
