static int flag = 0;
int matchPattern (char bitStream[]) //bitstream obtained from the function that returns 4 bits
{    
    
    //extract the first 4 bits of the 5-bit pattern value to be matched in the string Pattern 2

    
    if(flag==1 && bitStream[0]==Pattern[4[)     //When the next stream occurs match it with the last 
                                                                                                        bit of the pattern
      return 1;   

     if(!strcmpi(bitStream,Pattern2))
        flag=1;
