Encryption only needs to be checked for the stored data and not the moving data.

Explain how you would design a method, returning boolean, that determines if a string passed as a parameter satisfies this recursive definition.

< S > = < W > < W > < W > = a | b | a < W > | b < W >

To remove a node with a positive index k from a linked list,

A) decrement k by 1, and set the reference to the node to be removed to null B) start a reference r at the head of the list, walk r forward k steps, and then set r to null C) assign the successor reference in the node with index k to the successor reference in the node with index k-1 D) decrement k by 1, and then use recursion
