IN C++ or JAVA.PLEASE ,DO NOT WRITE ANY INPUT AND OUTPUT.DO NOT WRITE ANYTHING TO THE CONSOLE.

1.Write a function that accepts two character arrays as input and returns the one that is greatest in lexicographic (dictionary) order. Note the input is two character arrays, not two Strings! If the two arrays are equal return the first one. If either array is null, return null.

The signature of the function is:
char[ ] f(char[ ] a1, char[ ] a2)

Examples

{'d', 'o', 'g'} and {'c', 'a', 't'} returns {'d', 'o', 'g'}
{'a', 'b', 'd'} and {'b', 'b', 'c'} returns .{'b', 'b', 'c'}
{'d', 'i', 'g'} and {'d', 'o', 'g'} returns {'d', 'o', 'g'}
{'d', 'o', 'g'} and {} returns {'d', 'o', 'g'}
{'c', 'a', 'r'}, {'c', 'a', 'r', 't'} returns {'c', 'a', 'r', 't}
{'c', 'a', 'r'} and {'c', 'a', 'r'} returns {'c', 'a', 'r'}
{} and {} returns {}
{'a'} and {} returns {'a'}
{} and {'a'} returns {'a'}
null and {'a'} returns null

{} and {} returns {}
{'a'} and {} returns {'a'}
{} and {'a'} returns {'a'}
null and {'a'} returns null

If you're not supposed to write any input how does the function get the char arrays?
