Solution in C
Part 1 is a sort and a quick loop. Part 2 could be efficient with a lookup table but it was practically instant with a simple non-memoized scan so left it that way.
You are using some interesting techniques there. I never imaged you could use the result of == for adding to a counter.
But how did you handle duplicates in part 2?
Iโm not sure if I understand the question correctly but for every number in the left array I count in the right array. That means duplicate work but shrug ๐
