Logic Thinker,

You said, "There is not going to be an end of world."

Well, if it ended, would you know you were wrong? =^)

Thanks to both of you. Good discussion.

@Math Man

Of course, I didn't mean to teach You. :-)

But I just wanted to mention that the problem about determining happy numbers is to repeat an action on a sequence until the length of items making the sequence = 1.

Happy Holidays!

@ logic thinker

Yes. That is actually kind of what I did.

@Math Man,

You could do this app easier. Every digit is an character and the Text.SubString() for every character in text string: power up twice x * x and add to accumulator. Repeat, until accumulator is >=0 and <9. If accumulator = 1: happy, other: sad.

accum = 0

string = ...

for every charcter in string

accum = accum + (character * character)

'''''''''''''''' a character is a single digit, so only it's lenght is 1.

end for every

string = accum (Small Basic will make a string out of accum)

if accum > 9

repeat from the beginning, preserve the string

endif

if accum < 9 then

if accum = then

-> HAPPY

else

->SAD

endif

Sorry, when I put the link at the end of the sentence, it thought the question mark was part of the link. Here's the link: smallbasic.com/program

Ed, can you update the program link to smallbasic.com/program It just contains a minor bug fix. Thanks.

Please note, however, that if you enter '0' in the text box, it will crash. I will fix that as soon as I can.

I thought it was a good challenge because the check for happy numbers was recursive, so we had to be able to contain that recursion while still providing the correct answer to whether that was a happy number or not. The 6 smallest happy numbers are 1, 7, 10, 13, 19, and 23.
