| 2021-06-26 12:47:59 | <chisui> | ARGH, forgot to read the error message completely. |
| 2021-06-26 12:50:57 | <reedlepee> | chisui nvm...i found out what was wrong...I had to replace the "/" function with div..for rounding off as integers...now it's working :) |
| 2021-06-26 12:51:02 | <sshine> | reedlepee, instead of 'mod n 2 == 1', then 'odd n' |
| 2021-06-26 12:51:33 | <sshine> | reedlepee, you can also use `quot` instead of `div` since you don't care about negative rounding :) |

| 2021-06-26 12:53:03 | <reedlepee> | haskell is indeed very similar to gofer..now i think all FP might be similar to each other...thanks again guys..see ya! |

| 2021-06-26 12:53:49 | <sshine> | reedlepee, the 'n : ...' part belongs to the recursion pattern, but the '3*n + 1' vs. 'n `quot` 2' belongs to generating the next number. try and make a helper function: 'next n = if even n then n `quot` 2 else 3*n+1' and use 'next' in 'pink' :) |
