| Anton Antonov | How can I optimize (get faster execution times) for the following code: | 19:46 | |
| ``` | |||
| my @chars =['a' ... 'z'].roll(4); | |||
| my %init = @chars[*- 1] => %(ROOT0 => 1e0); | |||
| my %res = reduce(-> %a, $x { { $x => %a.push((ROOT2 => 1e0)) } }, (%init, |@chars[^(*- 1)].reverse)); | |||
| ``` | |||
| it produces `%res` like this: | |||
| ``` | |||
| {g => {ROOT2 => 1, q => {ROOT2 => 1, l => {ROOT2 => 1, c => {ROOT0 => 1}}}}} | |||
| ``` | |||
| gfldex | '@' ~ discord-user(694526400488669234.Str) With a nested structure you might be better of with custom classes then with Hash. As I understand it, reduce will copy ever growing Hashes into even bigger Hashes. | 21:55 | |
| Anton Antonov | '@' ~ discord-user(195453211409121280.Str) Thanks! I tried that first -- having a tree of objects. I thought moving to hashes would speed-up things. (Here is a more detailed description, in case you are curious: github.com/antononcube/Raku-ML-Tri...tion-notes ) | 21:58 | |

| lakmatiol | how would I go about checking if a string contains an uppercase letter, `[A-Z]` is not a valid raku regex, `[A..Z]` doesn't seem to do what I need it to | 22:43 | |
| Morfent | m:``` | 22:45 | |
| use v6; | |||
| say m:g/ <upper> / given 'abCdeFgh'; | |||
| ``` | |||
| m:``` | |||
| use v6; | |||
| say so m:g/ <upper> / given 'abCdeFgh'; | |||
| ``` | |||
| m:``` | 22:47 | ||
| use v6; | |||
| say so m:1st/ <upper> / given 'abCdeFgh'; | |||
| ``` | |||
| m:``` | 22:48 | ||
| use v6; | |||
| say so m:1st/ <.upper> / given 'abCdeFgh'; | |||
| ``` | |||
| '@' ~ discord-user(207089259730042881.Str) this is one way | |||
| m: ``` | 22:52 | ||
| say so m:1st/ <[ A..Z ]> / given 'abCdeFgh'; | |||
| ``` | |||
| m: ``` | 22:53 | ||
| use v6; | |||
| say so m:1st/ <[ A..Z ]> / given 'abCdeFgh'; | |||
| ``` | |||
| m:``` | |||
| use v6; | |||
| say so m:1st/ <[ A..Z ]> / given 'abCdeFgh'; | |||
| ``` | |||
| this will match ascii A-Z specifically |
