(HugeInteger Class) Create a class HugeInteger which uses a 40-element array of digits to store integers as large as 40 digits each. Provide methods Input, ToString, Add and Subtract. For comparing HugeInteger objects, provide the following methods: IsEqualTo, IsNotEqualTo, IsGreaterThan, IsLessThan, IsGreaterThanOrEqualTo and IsLessThanOrEqualTo. Each of these is a method that returns true if the relationship holds between the two HugeInteger objects and returns false if the relationship does not hold. Provide method IsZero. If you feel ambitious, also provide methods Multiply, Divide and Remainder. In the Input method, use the string method ToChar- Array to convert the input string into an array of characters, then iterate through these characters to create your HugeInteger. [Note: The .NET Framework Class Library includes type BigInteger for arbitrary sized integer values.]
