Wow! Thanks to everyone who posted their solution to last Week's Challenge here! It was great to see everyone's creativity and different approaches to solving a problem. We had some submissions for different locations (and hemispheres!), as well as some tweaks to put a unique analytical spin on the original problem. We also had some new Challengers! Woohoo!
This week's Challenge was inspired by a recent conversation I had with an Alteryx user at Inspire in London a few weeks ago. In this case, he wanted to figure out how many combinations of products he had in a dataset. We spoke about a few different approaches, and I'm curious to see how the Community responds to this Challenge. Have you had a use case where you've needed to accomplish something similar? What other tweaks can you think of that might make this Challenge relevant for other tasks?
The Input dataset contains a list of twenty (20) transactions. Each transaction contains a list of items that a customer purchased at the market. How many combinations of the same objects were purchased? In this case, the order does not matter. That is, the combination of "carrots, tea, shampoo" is the same as "shampoo, carrots, tea".
A straightforward answer wasn't coming to me, so this kinda happened EDIT: I realized on lunch break that crosstabbing my data made more sense. The unique tool solution would require you to check all the fields that come out of the crosstab so it's not dynamic.
