You are a medieval overlord tasked with designing a road network between three kingdoms placed on a \$9 \times 9\$ grid. A sample placement of kingdoms might look like this:
Non-commercial use of tileset by douteigami. Thanks!
The kingdoms make the following three demands:
The road network must...
Store eight bits on a punched card
code-golf binary encode
A little while back, data was frequently stored on punched card. A typical card would have 80 columns of 12 possible 'punch' positions. A plethora of encodings was used, each for their own specific purpose.
These days we like to think of ...
\$n\$-perfect numbers
A positive integer \$x\$ is an \$n\$-perfect number if \$\sigma(x) = nx\$, where \$\sigma(x)\$ is the divisor sum function. For example, \$120\$ is a \$3\$-perfect number because its divisors sum to \$360 = 3\times120 = 1+2+3+4+5+6+8+10+12+15+20+24+30+40+60+120\$, or \$92607...
Word Length-Sum Multiples
A port of my other question: Double Prime Words
Consider a word/string of n alphanumeric characters with sum of the characters, s, using their numeric position in the alphabet (a=1, B=2, c=3, etc.) or numeric value (0,1, 2, 3 - 9). Numeric characters should be taken at i...
I recently watched a Youtube video referencing a blogpost that shows how to generate a 3D spinning donut. The code itself is quite short, but I think it would be interesting to see just how little characters are actually required! (Also, looking forward to seeing the "Jelly donut").
For the sake ...
