Please tell the doubts in this Question

I want to print the directions in this one like: -
1: If element is traversed while moving Down.
2: If element is traversed while moving Right.
3: If element is traversed while moving Up.
4: If element is traversed while moving Left.

And Also 3 2 7 before 2 3 9
As 9 came first while traversing.
That’s why

How can I do this one.

Hey @cbcao263
You have to change line 10&11 a little bit
And I am not telling you what exactly ,figure that yourself :slight_smile:

   int dr[4] = {0, 1, 0, -1};

    int dc[4] = {1, 0, -1, 0};

Change them according to question
