It seemed very easy to me.
I just calculated the length and then divided the length by G to find the group length.
then in next step run a loop to length. and when it's divisible then reverse. :)

This may be the address of success.

Hello, i solved the problem and tested with some sample inputs, the outputs are always right, but when submit i got Wrong Answer, i can't identify what's wrong in the code.
Could you please give me a help to check what's wrong?

Code: Select all

int main()
{
    unsigned char nbrGroups=48, lines=0, offset = 0x00, out_offset=0,
    outstr[100], chars, count, groupSize, i;
    string str;

    //number of groups valid between 0 and 9
    while((nbrGroups >= 48) && (nbrGroups <= 57) && (++lines < 11))
    {
        cin >> nbrGroups;
        cin >> str;
        offset=0;
        out_offset=0;

        if(nbrGroups != 48)
        {
            //calculate the group size
            for(count=0;str[count] != 0x00; count++);

            //check if the total length is multiple of nbrGroups
            if(count%(nbrGroups-48) == 0)
            {
                groupSize = count/(nbrGroups-48);

                //go throught the groups
                for(count=0;count<(nbrGroups-48);count++)
                {
                    //invert the group
                    for(i=offset+groupSize;i != offset ;i--)
                        outstr[out_offset++] = str[i-1];

                    //set the position to the next group
                    offset+=(groupSize);
                }

                outstr[out_offset] = 0x00;
                cout << outstr << endl;
            }
        }
    }

    return 0;
}

Thanks in advance.

scanf("%s",&a);
l=strlen(a)/n;
for(i=0,j=0;i<n;i++)
{
for(k=0,t=0;t<l;k++,t++)

You can see the reason for your Compiler Error by clicking My Submissions.

In this case it's because strrev() isn't included in the judge's compiler. Write your own strrev().
Check input and AC output for thousands of problems on uDebug!
