RE: Little explorations with HP calculators (no Prime)
The following problem can be used to explore list functions. For example on the 50g. Useful list libraries that expands the built in ones: listExt ( http://www.hpmuseum.org/forum/thread-8555.html ) , goferlist ( https://www.hpcalc.org/details/6529 ) and lsort ( https://www.hpcalc.org/details/2828 ).


The problem: there are 100 blue Christmas balls and 40 white Christmas balls in a line, randomly ordered. There are Anna and Berta that needs balls for their Christmas trees.

They decide that Anna will pick a continuous chunk of the line of length 70, for example between the position 3 and the position 72, the rest will be picked by Berta.

Could they find a way to ensure that Anna and Berta pick both 50 blue balls and 20 white balls? If yes, is a special arrangement of the balls needed to achieve it?

Wikis are great, Contribute :)
