You are given N distinct points in a 2-D plane, numbered 1 through N. Your goal is to make the location of all the N points equal. To achieve this, you can do some operations.
In one operation, you choose an index i(1 <= i <= N) and a real number K and change the location of the i^{th} point in one of the following ways:
- Set (X_i, Y_i) = (X_i + K, Y_i)
- Set (X_i, Y_i) = (X_i, Y_i + K)
- Set (X_i, Y_i) = (X_i + K, Y_i + K)
- Set (X_i, Y_i) = (X_i + K, Y_i - K)
Find the minimum number of operations to achieve the goal: https://bit.ly/3yS4kFW.
