Background for this sort of niche joke: "Merge two sorted lists" is a classic CS algorithms quiz/interview question of extremely dubious real world utility. OL ("office lady") is Japanese for women whose job is keeping offices running efficiently by e.g. handling all the mail.

I get the joke. But seriously wondering if she ready does that ( and why). I know it used to be that you'd split the piles into "my city" vs "everywhere else" but didn't think ordering them was important. Maybe it is for her own cross check? (Then why by code and not by name?)
-
Because sorting by code should return the same order as last year except for people who have moved, allowing us to quickly compare against our address list and update the ones who moved.

"Now what do you do if both piles of post cards don't fit in memory?" ... oh wait...

We used to have to sort stacks of student assignments by student id after marking them in grad school. We never used merge sort. Radix sort was the way to go though
-
Yes! Radix sort isn't a comparison sort (which are limited to O(nlogn)), and as such, it can go down to O(n).
