Interview Prompt
A storage layer holds long status strings where the same character tends to repeat in stretches, and we want a compact form of `s`. Replace each stretch of one repeated character with that character followed by how many times it repeats in a row, and always write the count even when a character shows up just once.
Summary
Long stretches of sameness collapse into almost nothing.
