I'm supposed to resize an image given to me by half using arrays. I have no idea where to begin. I'm given a function 

```
public static int[][] resizeImage(int[][] original, int newWd, int newHt) 

```

and I'm supposed to use 2d arrays to map pixels from original to new image. Not sure if I'm giving enough info. I don't want the answer, just a hint or starting point, because I'm just not sure how to even start with this.
