In TCP communications there are 8 flags; FIN, SYN, RST, PSH, ACK, URG, ECE, CWR. These
flags have decimal numbers assigned to them:
FIN = 1
SYN = 2
RST = 4
PSH = 8
ACK = 16
URG = 32
ECE = 64
CWR =128
Example: To calculate SYN/ACK flag decimal value, add 2 (which is the decimal value of the SYN
flag) to 16 (which is the decimal value of the ACK flag), so the result would be 18.

Based on the above calculation, what is the decimal value for XMAS scan?
