| Day | Language | Experience | Technique highlights |
|---|---|---|---|
| 01 | Perl | Like being a wise man riding a camel! | Eminently readable. :) |
| 02 | R | Dataframe dark elven magic not to be repeated. | Row / column-wise manipulation |
| 03 | C | Still trying to fgets about it. |
ASCII conversions |
| 04 | Shell | Ugly but hard working. | Coordinate Math |
| 05 | Raku* | Not the camel I was looking for. | Regex, Stacks |
| 06 | PHP | Felt like 2003 and potpourri. | Sets |
| 07 | Kotlin* | I really wanted a ready-made Christmas tree. | Iterative search of recursive data |
| 08 | Julia* | Endearing at first but got awkward under the mistltoe | Grid search |
| 09 | Ruby* | Not the shiniest gem, yet treastures may lay within | Hashing |
| 10 | Go** | A fruit cake: filling, predictable, but somehow lacking heart | More iteration (yawn) |
| 11 | Groovy* | A glitter bomb: sparkly and bright, but gets everywhere | Closures |
| 12 | C++ | Like lighting the Christmas tree with real candles and heading to bed. | Dijkstra's algorithm |
| 13 | Javascript** | Hakuna matata! Slimy, yet satisfying! | Recursion |
| 14 | Nim* | A star! But still yonder afar! (maturing) | More grid search |
| 15 | Elixir* | Beautiful and glistening yet as rigid and unyielding as ice. | Functional: sets vs. ranges |
| 16 | C# ** | Many fine presents to unwrap under the MS Tree™. | Held-Karp, Generators |
| 17 | Dart* | Nifty! Every kind of ornament is being added, but where's my deep copy! | Simulation, cycle detection, Regex |
| 18 | F# * | Flexible & expressive but a little slow on the draw. | Functional, grid search |
| 19 | Lua* | A primitive weapon from a more civilized age. | Branch and bound + DFS |
| 20 | Typescript* | Beautiful wrapping paper, but I'm afraid to see what's inside. | Circular doubly linked list, Modulo |
| 21 | Scala | A supple staff for every kind of ninjitsu (except breaking loops) | Lazy Eval, Secant Root Finding |
| 22 | Swift** | Well-designed and expressive but bordering on complex. | Maze walk, 3D rotations |
| 23 | Python | I don't normally Python, but when I do, I go 3.10+ | Hash of Arrays, Closures |
| 24 | Java | Reasonable, understandable, but lacking bells and whistles. | DFS, branch and bound |
| 25 | Rust | A true gift to work with: expressive, rigorous, and blazingly fast. | Number base conversion |
* First time caller, long time listener
** Everyone deserves a second chance.
