Mistakes in your pluralsight course?

Hi Dan,

First let me tell you I learnt a lot with your course about data structures in Java. Thanks for that.

Correct me if I am wrong but I found a few mistake in the course:
Basic Queue:

• The contains and access method for loop should be i <= end and not i < end

BasicBinaryTree:

• In the delete method if the child has either a left or a right node, the existing node get deleted by error.

• In your ContactManagerApp when you delete "Abe Lincoln" you also delete "Sharee Glazer", "Dian Goheen" and "Ona Hynes"

I think the code int the delete method should be
if (child.getLeft() != null) { child.getParent().setRight(child.getLeft()); } else if (child.getRight() != null) { child.getParent().setRight(child.getRight()); } else { child.getParent().setRight(null); }
instead of just
child.getParent().setRight(null);

Please let me know if I am wrong but finding those mistake makes me slightly worried to be honest.

Thanks
