If the erroneous code received at LDPC decoder $C=\left[\begin{array}{cccccc}1& 1& 0& 0& 1& 1\end{array}\right].$ Find out syndrome and corrected codeword using bit flipping Algorithm where parity check matrix $(H)$ is given as

$\left[\begin{array}{cccccc}1& 1& 0& 1& 0& 0\\ 0& 1& 1& 0& 1& 1\\ 1& 1& 1& 0& 0& 1\end{array}\right]$
