3. [30 points] Binary-to-Decimal Conversion Write a function HW3_p3_bin to_dec0, that asks the user to Input an integer containing 0 s and is (i.e., a "binary" integer) and display/returns its decimal equivalent. Hint: Use the modulus and division operators to pick off the "binary" number's digits one at a time from right to left. Just as in the decimal number system, where the rightmost digit has the positional value 1 and the next digit to the left has the positional value 10 , then 100 , then 1000 , ete, in the binary number system, the rightmost digit has the positional value 1 , the next digit to the left has the positional value 2 , then 4 , then 8 , etc. Thus, the decimal number 234 can be interpreted as: 2100+310+41 The decimal equivalent of binary 1101 is: 18+14+02+11 Test your function by matching the expected output for the given inputs exactly. You can try the following test inputs (the instructor may run additional and/or different scenarios to test your code): Try
