You are given a hash map implementation that can store key-value pairs with the following operations/syntax. A pair (k,v) mapping k to v can be stored in a hash map H using the assignment syntax: H[k] = v and the value of a key k can be retrieved from H with the expression: H[k] Assume the value of the expression H[k] is -1 if the key k has not yet been added to the hash map. Using this hash map implementation and the syntax provided, write a pseudocode algorithm that checks whether all elements of a list are distinct. The input to your algorithm is an array A with n elements. The output should be True if all elements are distinct (no duplicates) and False if there is a duplicate. (Note: The hash map is a tool for you to use in your algorithm; you can create an empty one in your algorithm. The algorithm starts with the array A as input and nothing else.)

You are given a hash map implementation that can store key-value pairs with the following operations/syntax. A pair (k,v) mapping k to v can be stored in a hash map H using the assignment syntax: H[k] = v and the value of a key k can be retrieved from H with the expression: H[k] Assume the value of the expression H[k] is -1 if the key k has not yet been added to the hash map.

Using this hash map implementation and the syntax provided, write a pseudocode algorithm that checks whether all elements of a list are distinct. The input to your algorithm is an array A with n elements. The output should be True if all elements are distinct (no duplicates) and False if there is a duplicate.
