Exercise 2 [10 marks] - Binary to Decimal Conversion Write a code to input a binary number and convert it to a decimal number. For example: ex.1 - 1111 in decimal is 1*(243) +1*(2^2)+1*(241) +1*(240) = 8 + 4 + 2 + 1 = 15 in decimal. ex.2 - 10101 in decimal is 1*(244) +0*(243) +1*(242) +0*(241) +1*(240) = 16+0+4+0+ 1 = 21 in decimal. The number of digits in the binary number has no fixed size (user can enter any number of bits). Sample Output: Enter the binary number 10 The decimal number is: 13
