What is the most important idea in this section of the passage?
Facial recognition should be used
D) along with typed passwords for the
best possible security.
The fact that devices will soon be able
to recognize brainwaves is interesting
but requires much more testing.
Typed passwords are already being
Dreplaced, and data like brainwaves
might replace them more in the future.
Although typed passwords are being

Assume you need to test a function named inorder. the function inorder receives three int arguments and returns true if and only if the arguments are in non-decreasing order: that is, the second argument is not < the first and the third is not < the second. write the definition of driver function testinorder whose job it is to determine whether inorder is correct. so testinorder returns true if inorder is correct and returns false otherwise. for the purposes of this exercise, assume inorder is an expensive function call, so call it as few times as possible!
