LDPC: Bit-flipping decoding [Hard decision]

I I am working with LDPC in which i want to know whether Bit-flipping algorithm detects more than one error bit through hard decision algorithm. I have already gone through the LDPC tutorials and video lecture of decoding concept. But still i am not clear.

I need to implement LDPC decoder to correct more than one error bits using hard-decision m-passing algorithm. So, please anyone explain me what i need to do to correct more than one error bit. I need logic to implement the LDPC.

One_Bit Flipping : For 1st codeword its showing incorrect result? Please anyone explain me.

Thanks in Advance.
