Rules:
- Normal 5x5 sudoku rules apply, i.e. each row and column has to contain the digits from 1 to 5 once each.
All clues outside the grid are both Full Rank and X-sum clues.
- Full Rank: A value outside of the grid represents the rank of the number formed by reading the digits in that row or column from that direction, where (1) is the lowest such row or column and (20) is the highest.
N.B. If two ranks are tied, the value in both external cells is the lower of the two ranks being shared. For example, if the lowest four ranks are "12345", "12435", "12435" and "12534", the values in the relevant external cells would be (1), (2), (2) and (4) respectively.
- X-sums: A clue outside of the grid indicates the sum of the first X digits in the respective row or column where X is the first digit seen from the clue.
Here you can solve the puzzle online:
Solution code: Column 4 from top to bottom (5 digits in total)

I almost thought there was an error with 11, but then I remembered to think about more than the first three digits XD

Thank you for your comment, garycblack! As you say, all digits matter. :) I hope you had a fun solve.

Thank you for this nice puzzle, dear sujoyku! :)
It took me some time to understand the Full Rank rule because it was my first sudoku of that sort. As I struggled, I gave it 3 stars, although it is probably a lot easier as soon as one is familiar with this rule.
I have to say, it is an interesting new rule that requires new thinking. Thank you very much!

You are much welcome, Lenivaya_Joppa, thank you for your comment! Of course, difficulty always depends on familiarity with the constraints. So I am completely fine with you rating it higher. I am glad that you enjoyed it.
Kind regards, sujoyku

I don't understand the Full Rank rules.

You consider the rows and columns as 5-digit numbers (read in the direction starting from the clue). That gives you 20 such numbers and the ranks tell you the order from lowest (1) to highest (20).

Alright, I think I'm finally getting a better hang on these full-rank puzzles...
**
Thank you for your comment, dzamie! It was my goal that this was an approachable full rank puzzle. Before participating in the prompt, I had never worked with this constraint, so I wanted to make it accessible for people with a similar (lack of) experience.
Kind regards, sujoyku

Not only did I enjoy the actual puzzle, but I also enjoyed the bonus puzzle I made for myself in my first attempt to solve it, when I forgot how to add digits up to 10 and made them add up to 9 instead.
**
Thank you for commenting, MaizeGator! I can relate 100%, vividly remembering when I asked Flinty for a hint and it turned out that 1+4+8 did not equal 12...
I am glad that you enjoyed the puzzle.
Kind regards, sujoyku
