HI,I need help on the below question.

You receive the following 64 bits (expressed in hexadecimal) containing a DES key:

7A 26 DF 9E 23 57 E6 F4

(a) What is the 56-bit DES key (expressed in hexadecimal)?
(b) List the first five (5) 48-bit round keys (in hexadecimal) that will be generated from this key.
