PYTHON

Consider the following two hash functions. Let U be the universe of strings composed of the characters from the alphabet PYTHON Consider the following two hash functions. Let U be the universe , and let then function of strings composed of the characters from the alphabet , and let return the index of a letter then function return the index of a letter , e.g., f(a) =, e.g., f(a) = 1 and f(Z) = 26. Finally, for an m-character string 1 and f(Z) = 26. Finally, for an m-character string ^ m, ^ m, define define , where is the number of buckets in the hash table. For the other hash function, let the function return , where is , where a uniform random integer, , and define . That is, the first is the number of buckets in the hash table. For the other hash function, let the function hash function sumps up the index values of the characters of a return string x and maps that value onto one of the bucket, and, where the second hash function is a universal hash function. (b) Produce a is a uniform random integer, histogram showing the corresponding distribution of hash locations for each hash function , and define when SMITH JOHNSON WILLIAMS JONES BROWN DAVIS MILLER WILSON MOORE TAYLOR ANDERSON THOMAS JACKSON WHITE HARRIS MARTIN THOMPSON GARCIA MARTINEZ ROBINSON CLARK RODRIGUEZ LEWIS. That is, the first hash function sumps up the index values of the characters of a string x and maps that value onto one of the LEE WALKER HALL ALLEN YOUNG HERNANDEZ KING WRIGHT LOPEZ HILL SCOTT GREEN bucket, and the second hash function is a universal hash function.
