Suppose you have a simple hashing system for storing integers that just uses a compression function to determine the array slot to use and uses linear probing for collision resolution. collision(s) occur if the size of the array is 20 and the following sequence of integers is added: 5 10 15 20 25
Each time the chosen array slot is already occupied should be counted as a collision; in other words, multiple collisions can occur when adding a single element due to collisions happening while linear probing. Your answer should be a number.
