[elisrich]

This thread is for posting solutions to “Just KNIME It!” Challenge 28. This week we will do a little bit of logic building and produce a left triangle star pattern!

Here is the challenge: Just KNIME It!

Feel free to link your solution from KNIME Hub as well!

And as always, if you have an idea for a challenge we’d love to hear it! Tell us all about it here.

Here’s my solution to Challenge 28

justknimeit-28 – si_daniel_a

The star is coming from the workflow variables, that’s why I only used Variable to Table Row Node as my source

Hello KNIMErs,

Here is my solution to #justknimeit-28 :

KNIME Hub > gonhaddock > Spaces > Just_KNIME_It > Just KNIME It _ Challenge 028

My initial approach was based on Recursive Loop as well (Rule Engine supported); as it’s been already covered, I’ve changed to Column Loop.

As always on Tuesdays, here’s our solution to #justknimeit challenge 28!

Challenge 28 - Left Triangle Star Pattern - Solution – elisrich

As you can see, we used a counting loop to build our pattern iteratively. However, other loops or even no loops solve the challenge, too!

Hope to see you tomorrow for a new challenge!

Hello Knimers,

here is my take on the challenge.

justknimeit - 28 - Raffaello Barri – lelloba

I used variables, so you can change the character and the number of rows of the figure.

Have a nice evening,
