(15C) Find narcissistic / Armstrong numbers

Hi, jonakeys,

Welcome to the MoHPC forum !

I am the one who posted that S&SMC #3 so thank you for your interest in my production of some 22 years ago.

If you'd like to see many more of my challenges (and in particular many HP-15C mini-challenges,) you can find them all in the HP Calculator Challenges Section at my site.

Quote:I'm sure it can be faster/more efficient, so if you see room for improvement, feel free to comment so I can learn!

The thread for my S&SMC #3 contains tons of solutions and comments on techniques to optimize the search, so you can try those ideas, collected in this 20-page PDF document.

One of these days I might post an UBASIC program I wrote at the time which can find all such numbers up to 39 digits long in a very few hours on pretty ancient hardware.

Again, welcome and best regards.

V.
