write an application that will allow the user to enter one of two types of input: an 8-bit string or a decimal integer (-128, +127).

Binary String Input: If the user entered a binary string, your program should calculate and display the decimal equivalents of the binary string, assuming that it could represent an integer using either signed magnitude, ones complement, twos complement, or excess-128 notation.

Decimal Input: If the user entered a decimal integer, your program should calculate and display the equivalent 8-bit strings used to represent the integer value using signed magnitude, ones complement, twos complement, and excess-128 notation.

Your program should implement data validation and display properly formatted and labeled output.
