Problem Statement

Noya came to a shop that sells plenty of each of $4$ types of fruit $0,1,2,3$, and bought $4$ fruits so as to satisfy at least one of the following conditions.

  • The $4$ fruits are all of the same type.
  • The $4$ fruits consist of $2$ fruits each of $2$ types.
  • The types of the $4$ fruits are all different.
