WebBinary Digit Escaping. Let F be a procedure that transforms a binary number X to Y. In F we go through digits from the Most Significant Bit (MSB) of X to its Least Significant Bit (LSB) and performs following operations: If MSB is 0, the transformation fails unless X is 0. If it ever finds two consecutive 0s in X, the transformation fails.
