A *palindrome* is a word, number, phrase, or other sequence of characters which reads the same backward as forward.
- Example: 123321, 4321234
Write a program that determines if an integer number is a [palindrome](https://en.wikipedia.org/wiki/Palindromic_number).
- Write a function called `reverse` that takes a positive integer and returns the reverse of that number.
- For example: If the input for the function is `1234`, it should
return `4321` as an integer, not string.
- Write a function called `isPalindrome` that tests if the number is a
palindrome, then returns true, else returns false.
- Hint: Use the `reverse` function. If a number and its reverse are the same, then it is a palindrome.
Use below test driver to check correctness of your program.

Test Driver
```c++
#include <iostream
#include <iomanip
using namespace std;
unsigned int reverse(unsigned int);
bool isPalindrome(unsigned int);
int main()
{
cout << boolalpha << "123321 is a palindrome: " << isPalindrome(123321) << endl;
cout << "4321234 is a palindrome: " << isPalindrome(4321234) << endl;
cout << "1003003001 is a palindrome: " << isPalindrome(1003003001) << endl;
cout << "100300300 is a palindrome: " << isPalindrome(100300300) << endl;
return 0;
}
```
