I have dropped off my daughter at “Coding Club” which sounds like an excellent idea! Looking forward to finding out what they did. That reminded me to post a couple more Euler solutions. Not pretty, but they worked.
Euler 9 only took about 5 minutes to do, there are lots of possible optimisations!
Incidentally, the coding club started with html and the pupils made a web page (manually).
Also, further to my post below, the easiest way to move a VM from vSphere to VMware Workstation, is of course, copy the files. It is running very well.
