Write a function that parses a binary number as a string into a decimal integer. Use the function header:
def binaryToDecimal(binaryString):
For example, binary string 10001 is 17 (1 x 2⁴
+ 0 x 2³
+ 0 x 2²
+ 0 * 2 + 1 =17)
So, binaryToDecimal("10001") returns 17.
Write a test program that prompts the user to enter a binary string and displays the corresponding decimal integer value.
