I need a small advice in codechef long challenge January encoding the string.

Question

I have wrote most of the program but there is a small bug when there is more than 4 nos. i.e. 8 or more ,it encodes the first four nos. correctly but prints the same value for the next 4 nos.I have incremented the value of i after for loop by 4 so that it starts from the next four nos. But in the end I am getting same answer as the previous one. I have been looking at it all day and I wouldn't have asked if there was no other way.pls share some advice.

for(int y=0;y<z;y++)

            for(int i=p;i<j;i++)

            {

                if(mid==1)

                    mid=1;

                else

                    mid=mid/2;

                if(a[i]=='0')

                    l=l-mid; //8-4,4-2,2-1

                else

                    l=l+mid;

            }

            if(l>=1)

                l--;

            cout<<ar[l];

            p=p+4;
