The task in kotlin is to sort by the 1st column and display the 2nd column, without the last five lines, tell me at least an idea how to do it, I recently began to study kotlin ....

Answer 1

1) Split into lines (split)
2) Parse each line with a regular expression (regexp) and add it to an object with two fields (first and second)
3) Sort the list of objects (sort)
4) Take the required number of objects from the list (take / drop)
...
Profit!
