Edge case question

What happens when the input is empty? Should we handle this case?

Need help with this challenge

I'm stuck on this problem. Can someone give me a hint on the approach?

Solution approach

Here's how I solved this challenge: 1. First, I analyzed the problem 2. Then I implemented the solution 3. Finally, I optimized it Hope this helps!

Optimization tips

You can optimize this solution by using a hash map instead of nested loops. This reduces time complexity from O(n²) to O(n).
