  1. Initialize a set to store all points for constant time look-up.
  2. Initialize a variable to store the minimum area found, set it to infinity initially.
  3. Iterate through all pairs of points in the input array.
  4. For each pair, calculate the potential rectangle's area if the points are diagonally opposite.
  5. Check if the other two points of the rectangle exist in the set.
  6. If they do, update the minimum area if the current rectangle's area is smaller.
  7. After checking all pairs, return the minimum area found or 0 if no rectangle was found.
