useMemo Cache Hits

MediumReact Hooks

useMemo recomputes only when deps change. Input: one line per render with the dep value (a single number). Print two lines: total computations, total cache hits.

Input: one dep per line. Output: computations, then hits.

Your program reads from stdin and prints to stdout.

Example 1

Input: 1 1 2 2 2

Output: 2 3
