| 2025-02-09 06:57:23 +0100 | <ski> | better to use that, rather than `getLine' & `read' |

| 2025-02-09 06:47:55 +0100 | <tri> | ah! thank you. It's been a long time since I last used Haskell :) |
| 2025-02-09 06:46:09 +0100 | <monochrom> | Conversely, I see people writing in C "return(x+y)" all the time. :) |
| 2025-02-09 06:45:36 +0100 | <int-e> | tri: keep in mind that in Haskell `return` is a function, not syntax. |

| 2025-02-09 06:43:44 +0100 | <int-e> | you can drop the @[Int], but you still need parentheses |

| 2025-02-09 06:43:01 +0100 | <int-e> | that's the m0 a0, more or less |

| 2025-02-09 06:42:32 +0100 | <c_wraith> | Add parens |
| 2025-02-09 06:42:20 +0100 | <tri> | how could I fix this please? I don't understand the error message, especially m0 and a0 |

| 2025-02-09 06:06:27 +0100 | <tri> | hmm ok |
| 2025-02-09 06:01:09 +0100 | <monochrom> | Now to probe the boundary of your understanding, "g xs ys = sum (zipWith f xs ys)" can still be simplified with (.), but only as: g xs = sum . zipWith f xs |

| 2025-02-09 05:57:46 +0100 | <tri> | so that's why zip was failing because it is a 2-input function |
| 2025-02-09 05:57:26 +0100 | <tri> | oh the (.) is actually a function, which takes two 1-input functions |

| 2025-02-09 05:45:48 +0100 | <tri> | yea that works, I'm just trying to make it work using function composition. I forgot what concept force me to use 1 input function to compose, I have to look it up |
| 2025-02-09 05:44:02 +0100 | <monochrom> | Do you accept: getTotalDistance xs ys = sum (zipWith (\(left, right) -> abs $ left -right) xs ys) |
| 2025-02-09 05:43:45 +0100 | <tri> | seems like I can only compose 1 input function... |

| 2025-02-09 05:36:48 +0100 | <tri> | it has something to do with 2 parameters passing into zip, but I can't really explain |
