Please clearly explain your answer. Show all steps and identify the answer.

A message is encoded using the Hamming code and is transformed through a channel. The reciver receives the following encoded codeword:

position: 1 2 3 4 5 6 7 8 9 10 11

Codeword: 1 0 1 0 1 0 0 1 0 0 1

Determine whether any single error has occurred during the transmission. If yes, determine the position tha it occurs. What is the original message (excluding check bits)? You must show your steps clearly.
