O(n²) That Works vs O(n log n) Nobody Can Maintain

Description

A two-panel Captain America before/after meme captioned 'Works perfectly. Good luck maintaining it.' Top panel: scrawny pre-serum Steve Rogers (Chris Evans) next to red stylized text 'O(n²) solution that works'. Bottom panel: the muscular post-serum Captain America beside 'O(n log n) solution nobody on the team can understand'. The meme inverts the usual glorification of algorithmic optimization: the naive quadratic solution is the weakling, but the impressive optimized version is a maintainability liability - capturing the senior-engineer tension between Big O elegance and code the rest of the team can actually reason about, where premature optimization trades readability for benchmarks nobody asked for at the current data scale

Runtime improved from O(n²) to O(n log n); bus factor regressed to O(1).

The O(n!) written by AI that doesn't work and nobody on the team can understand.

Sounds like skill issue, grind LeetCode harder

if it works don't touch it
