Please write the following 4 modules in Verilog separately.

1. ONE-HOT to 4-BIT_INTEGER module that converts its 16-bit one-hot input to the corresponding 4-bit integer.

2. THERMO TO ONE-HOT module that converts its 15-bit thermometer input to the corresponding 16-bit one-hot value.

3. THERMO TO BINARY module that converts its 15-bit thermometer input to the corresponding 4-bit output integer.

4. SECOND LARGEST module that accepts as input four 15-bit thermometer codes and outputs the second largest one.
