Collision in hashing:

• Generally, hashing algorithm will produce different hash code for different values but, it is not usually ideal. Sometimes, a hashing algorithm will produce the same hash code for two objects that are not equal, is called as collision.
• The “HashSet” performs two tests in collisions,
  • One using the “HashCode()” method...
