time squaresums.sh 60000000 -> 1, 9, 99, 10954, 59999999 == real 0m0.027s
actually solvable in under 90 mins using a shell script thats about 50x 'better' than 12s.
dudes...

why would that make a diff, absolute size is meaningless. its about the geom of the input.
time squaresums.sh 100000 -> 1, 2, 4, 13, 447, 99999 == real 0m0.028s
time squaresums.sh 1000000000000 -> 5, 22, 1261, 1414213, 999999999999 == real 0m0.023s

this result is from my shell-script.
its not hard to beat when you're not being so literal. :)

wow. immediately disliked 7 of the 10 other shell solutions. :)

great puzzle, lmao, only realized what the quesion was after solving the general problem.

dismissed sed and hammered out/nailed the array solution before i knew sensei thought they were hard :)

hahahaha! its my 2nd day here and i thought that doing a bash kata
meant that i had to restrict my self to bash! hahahaha. great joke sensei!

next up generating .elfs via echo -e!
