Dumping trees to a terminal in a compact, readable form is an invaluable aid to developing and debugging tree-based algorithms. The following demonstrates a mechanism for doing this for array-based binary trees:

A couple of examples:

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
