Similar Problem to CF Round 1054 (Div. 3) E

I noticed that 2149E — Subarrays with Exactly K from the just-finished contest is similar with LeetCode 992 — Subarrays with K Different Integers

The main twist here is that Codeforces adds the extra condition with [l,r] to the LeetCode version.

if you're upsolving E, I'd recommend trying LC 992 first :)
