Made my first-ever problem on Codeforces! 🥳
(It’s not in an official contest)
I thought making a question was just writing a problem and a few test cases but it's not that simple. Tbh, my real success would not be reaching Expert or CM but writing questions for a real contest
Some people spent their childhood 'training' while I was directionless, just existing, no hobbies nothing.

Just realised,
std: :map is not the best idea to track frequency (when array values bounded by 2N)
just use lookups like: tracker_a[a[i]],
This will drop the tc from, O(log N) to O(1)
