Yet another poorly specced, poorly named, trivial task. |
|||
How many integers in base 16 cannot be written without using a hexadecimal digit? All of them. Or none of them. |
|||
Base 16 is not hexadecimal. Hexadecimal is ''an implementation'' of base 16. |
|||
<lang perl6>use Base::Any; |
|||
set-digits <⑩ ⑪ ⑫ ⑬ ⑭ ⑮ ⑯ ⑰ ⑱ ⑲ ⑳ ㉑ ㉒ ㉓ ㉔ ㉕>; |
|||
say (7**35).&to-base(16); |
|||
# ⑭㉒⑱⑩⑰⑰⑳⑮⑱⑳⑩⑳⑱㉒㉑⑰㉒⑫⑭⑲⑯⑩㉔⑮⑰</lang> |
|||
How many of those glyphs are decimal digits? And yet it '''is''' in base 16, albeit with non-standard digit glyphs. So they '''all''' can be written without using a hexadecimal digit. |
|||
But wait a minute; is 2 a hexadecimal digit? Why yes, yes it is. So ''none'' of them can be written in hexadecimal without using a hexadecimal digit. |
|||
Bah. Show which when written in base 16, contain a digit glyph with a value greater than 9: |
|||
<lang perl6>say (0..500).grep( { any |.map: { .polymod(16 xx *) »>» 9 } } ).batch(20)».fmt('%3d').join: "\n";</lang> |
