Footnotes

  1. Project Euler Problem solved through ProjectEuler+ Challenge code 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

  2. Previously named "Multiples of 3 and 5": https://projecteuler.chat/viewtopic.php?t=7316. The ProjectEuler+ Challenge still has this name.

  3. Project Euler Problem (Descriptions /) Titles previously did not use title case: https://web.archive.org/web/20230528105433/https://projecteuler.net/archives. This is still reflected in the ProjectEuler+ Challenge name. 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

  4. Project Euler Problem solved through ProjectEuler+ Challenge code, with adjustment of constant variable(s) 2 3 4

  5. The ProjectEuler+ Challenge has a different name: "Number to Words"

  6. Project Euler Problem solved through ProjectEuler+ Challenge code, optionally using the file given as part of the problem

  7. No code necessary 2

  8. No corresponding ProjectEuler+ Challenge yet 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
