(Separating Digits) Write methods that accomplish each of the following tasks:
a) Calculate the integer part of the quotient when integer a is divided by integer b.
b) Calculate the integer remainder when integer a is divided by integer b.
c) Use the methods developed in parts (a) and (b) to write a method displayDigits that receives an integer between 1 and 99999 and displays it as a sequence of digits, separating each pair of digits by two spaces. For example, the integer 4562 should appear as
4 5 6 2
Incorporate the methods into an application that inputs an integer and calls displayDigits by passing the method the integer entered. Display the results.
