Create a class HugeInteger which uses a 40-element array of digits to store integers as large as 40 digits each.
Provide methods input, output, add and subtract. For comparing HugeInteger objects, provide the following methods: isEqualTo, isNotEqualTo, isGreaterThan, isLessThan, isGreaterThanOrEqualTo and isLessThanOrEqualTo.
Each of these is a predicate method that returns true if the relationship holds between the two HugeInteger objects and returns false if the relationship does not hold. Provide a predicate method isZero. If you feel ambitious, also provide methods multiply, divide, and remainder. [Note: Primitive boolean values can be output as the word "true" or the word "false" with format specifier %b.]
