Question

In an array-based implementation of a dictionary, if you represent the entries as an array of objects that encapsulate each search key and corresponding value, how many pointers will you use per array entry?

a. 3
b. 4
c. 2
d. 1

Answer 1

The answer is "Option C".

Step-by-step explanation:

Dictionary is a set of unsorted data values, that is used to save data like a map and which contains a key: value pair in comparison to many other types of data, which only carry a specific number as just an element.

If we use Dictionary as an array so, it uses a two-pointer variable, one for hold key, and the second is used to hold its value.
