Question

Give the change to line 7 of the Unsorted Array structure’s Fetch algorithm shown below that would unencapsulate the structure after Fetch operation is completed. [edit: There is no more information, this is the question. Only need to edit line 7 to make it unencapsulate the structure after Fetch operation is completed ]

Unsorted Array Fetch Algorithm 1. 2, 3, Ilaccess the node (assumes the node is in the structure) i=0; while (targetKey I= data [i].key()) 5. 6. I l/ return a copy of the node to the client 7. return data[i] deepCopyO Note: This is a single line of code replacing line 7

Answer 1

There are three ways to return the line 7 as shown above. They are as below:

1. Using Arrays.copyOf

return Arrays.copyOf(data, data.length);

2. Using System.arraycopy

return System.arraycopy(data,0,newData,0,data.length);

3. Using clone method

return data.clone();

Hence, these are the three methods that one can try on to return a copy of the node to the client.
