Write the code necessary to find the largest element in an unsorted array of integers. What is the time complexity of this algorithm?
What will be an ideal response?
```
int max;
if (intArray.length > 0)
{
max = intArray[0];
for (int num = 1; num < intArray.length; num++)
if (intArray[num] > max)
max = intArray[num];
System.out.println (max);
}
else
{
System.out.println ("The array is empty.");
}
The algorithm examines each of the array. If there are n elements in the array, the time complexity of the algorithm is O(n).

Write an example method that overrides the + operator to create a new book whose title is a concatenation of the titles of two books. For example, if the first book's title is "The Adventures of Tom Sawyer" and the second book's title is "The Adventures of Huckleberry Finn", the concatenated title will be "The Adventures of Tom Sawyer and The Adventures of Huckleberry Finn". Assume the book class is defined as:class Book{public Book(string title){Title = title;}public string Title {get; set;}}
