答案

namespace RLE {
  export type Encode<S extends string> = any
  export type Decode<S extends string> = any
}

验证

import type { Equal, Expect } from '@type-challenges/utils'

type cases = [
  // Raw string -> encoded string
  Expect<Equal<RLE.Encode<'AAABCCXXXXXXY'>, '3AB2C6XY'>>,

  // Encoded string -> decoded string
  Expect<Equal<RLE.Decode<'3AB2C6XY'>, 'AAABCCXXXXXXY'>>,
]
