Decimal to Binary Conversion

Given a non-negative decimal number as a string, convert it to its binary representation with a prefix (0b). The binary representation is computed by repeatedly dividing the number by 2 and collecting the remainders. For example, the decimal number 10 converts to (0b1010), and 255 converts to (0b11111111). Your solution should read the input from standard input and write the result to standard output.
