### Hex to Binary Conversion

This is just the reverse of the previous conversion.

Step 1: for each Hex character, transcribe the 4 bit binary number corresponding to the symbol.

Step 2: if you left spaces between the bits, remove them.

Example: DE32 gives 1101 1110 0011 0010.

**Exercise**: what binary number corresponds to 123ABC?
