How in the hell does anyone fโ up so bad they get O(n!ยฒ)? ๐คฏ That's an insanely quickly-growing graph.
Curious what the purpose of that algorithm would have been. ๐
Let me take a stab at it:
Problem: Given two list of length n, find what elements the two list have in common. (we assume that there are not duplicates within a single list)
Naive solution: For each element in the first list, check if it appears in the second.
Bogo solution: For each permutation of the first list and for each permutation of the second list, check if the first item in each list is the same. If so, report in the output (and make sure to only report it once).
lol, you'd really have to go out of your way in this scenario. First implement a way to get every single permutation of a list, then to ahead with the asinine solution. ๐ But yes, nice one! Your imagination is impressive.
