Cycle Finding Approach
- Create a mapping of each person to their partner and a mapping of each person to their current position.

- For each pair, if they are not a couple, find the cycle they are in.
- For each cycle found, increment the swap counter by the size of the cycle minus one.
- Return the swap counter as the result.
