Is the problem of searching through a binary tree for a particular value a polynomial problem? Justify your answer. Design an algorithm for calculating the Fibonacci series of a given number. Is your solution efficient? Is your solution a polynomial or nonpolynomial one? Give an example of a scenario in which there is a fine line of distinction between deterministic and nondeterministic algorithms.
