2. Gray code to BCD code converter

To convert Gray code to BCD (Binary Coded Decimal), you need to follow these steps:

1. Convert Gray code to Binary: The most significant bit (MSB) of the binary code is the same as the MSB in the Gray code. For the rest of the bits, if the corresponding bit in the Gray code is 1, the bit in the binary code is the complement of the bit above it in the binary code. If the corresponding bit in the Gray code is 0, the bit in the binary code is the same as the bit above it in the binary code.

2. Convert Binary to BCD: Once you have the binary number, you can convert it to BCD. Each decimal digit (0 through 9) is represented by a group of 4 binary bits. Start from the rightmost (least significant) binary digit and group them in sets of 4. If you have
