Problem

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

Say it once, then say how many times it stayed.
