Implement the following method to show a seam on a Picture:
This method should return a copy of this with the lowest-cost seam, as computed by computeSeam, shown in red. To do this, you’ll probably want to start by
int[] seam = this.computeSeam();
Picture newPicture = new Picture(this);
From there, you’ll need to loop through and change some of the pixels of newPicture to be red – namely those on the seam! Here is an example from the okinawa.jpg image:
When you complete this part, all of the tests from PictureTest_ShowSeam.java should pass.
