Manually simulate the Fletcher algorithm (Figure 10.18) to calculate the checksum of the following bytes: (2B) 16

Question:

Manually simulate the Fletcher algorithm (Figure 10.18) to calculate the checksum of the following bytes: (2B)₁₆, (3F)₁₆, (6A)₁₆, and (AF)₁₆. Also show that the result is a weighted checksum.
