I need 7a. thank you

7. The following problems deal with working with bit masks. (a) Define an 8 bit mask that you can use with a binary operator to set the MSB of an 8 bit value to 1, leaving all the other bits as they were. Example: Given 01101101, your mask when applied should result in 11101101. What operation do you need to use with the mask you designed? (b) Determine the hexadecimal value of a mask that can be inclusively ORed with the bit pattern in
