Design a an application that inputs an integer containing only Os and 1s (i.e., a binary integer) and prints its decimal equivalent. [Hint: In the binary number system, the rightmost digit has a positional value of 1, the next digit to the left a positional value of 2, then 4, then 8, and so on. The decimal equivalent of binary 1101 is 1*1 + 0*2 +1* 4+1*8, or 1 + 0 + 4 + 8 or, 13.]
