Write a program in java which takes as input a string representation of an unsigned hexadecimal number in 32 bits and returns the positive integer that is the base 10 equivalent.
You do not need to worry about negative values for this question
You can use a dictionary, or brute force to convert hex digits to numbers (i.e. write a function with a bunch of if statements or a select statement to deal with digits A-F. or store the values 0-F as keys in a dictionary with the values being the number the digit represents.
For both programs, all non-decimal numbers should be assumed to be 32-bit. When inputting or outputting binary or hex, please make sure the numbers represented are full 32-bit numbers. Do not leave off the leading 0’s or 1’s.
Binary: 00001111110111010101111111011101 (32 digits) Hex: 0FDD5FDD (8 digits long)
