## Question

A) Develop body of the method public static int numberOfDigits(int n)
The method takes a positive integer number, n, as its argument and returns number of digits of n.
For example if n = 3465, then the method should return 4.

B) Then use the method numberOfDigits you have developed in part A, and develop the body of following method
public static int leftRotate(int n) that takes a positive integer number, n, and left-rotate it one digit.
For example if n is equal to 36498, then the method should return 64983.
