The function add stores the positive integer value specified by the argument in the global integer-type array hashArray. It returns true if the value has been stored, and returns false if the value could not be stored. Here, which element of hashArray the integer value should be stored in is determined by using the functions calcHash1 and calcHash2.
The procedure test calls the function add to store positive integers in hashArray. The content of hashArray immediately after the processing of the procedure test has finished is blank.

Cosine similarity is a measure of the similarity of the directions of two vectors. The function calcCosineSimilarity receives the real-type arrays vector1 and vector2, each of which has n (n ≥ 1) elements, and returns the cosine similarity of the two arrays. When the array vector1 is {a1, a2, …, an} and the array vector2 is {b1, b2, …, bn}, the cosine similarity is calculated by the following formula. Here, it is assumed that neither the array vector1 nor the array vector2 has 0 stored in all of its elements.
a1b1 + a2b2 + … + anbn√a21 + a22 + … + a2n √b21 + b22 + … + b2n
