Strange. Can you give me some test data for my C++ program?
if ((sir[0]==sir1[1] && sir[1]==sir1[0] && sir[2]+sir[3]==sir1[2]+sir1[3]) ||
        ((sir[3]==sir1[1] && sir[2]==sir1[0]) && (sir[0]==sir1[2] && sir[1]==sir1[3])))
        cout <<"equal";
    else
    {
        if (sir[0]==sir1[2] && sir[1]==sir1[3] && sir[3]==sir1[1] && sir[2]==sir1[0] )
            cout <<"equal";
        else
        {
            if (sir[0]==sir1[1] && sir[1]==sir1[3] && sir[2]==sir1[2] && sir[3]==sir1[0])
                cout <<"equal";
            else
            {
                if (sir[0]==sir1[0] && sir[1]==sir1[1] && sir[2]==sir1[2] && sir[3]==sir1[3])
                    cout <<"equal";
                else
                {
                    if (sir[3]==sir1[0]&&sir[2]==sir1[1]&&sir[1]==sir1[2]&&sir[0]==sir1[3])
                        cout <<"equal";

            else
                cout <<"different";
                }
            }
        }
    }
My code seems legit. Tnx.
All tests posted on the Forum (Discuss work for my program)
Again working.

GRBY
YGBR
should be equal.

Here: sir[2]==sir1[3] && sir[3]==sir1[2]

YGBR
GBRY
should be different. :D

sir[0]==sir1[1] && sir[1]==sir1[0]

RRRR
RRGG
your algorithm's output is equal. :)

(sir[3]=sir1[0]&&sir[2]=sir1[1]&&sir[1]=sir1[2]&&sir[0]=sir1[3]) - is equal

Try it: RGBY
        YBGR

I'm not sure it's right, but you can try. :)
