Suppose a very large sorted list is stored in external storage. Assuming that this list cannot be brought into internal memory, develop a searching algorithm that looks for a key in this list. What major factor(s) should be considered when an external search algorithm is developed? Define the major fac\(\operatorname{tor}(s),\) analyze your algorithm, and show the results using order notation.
Write an algorithm that finds the largest key in a binary search tree. Analyze your algorithm, and show the results using order notation.
Show that the average-case time complexity of Interpolation Search is in \(\Theta(\lg (\lg n)),\) assuming the keys are uniformly distributed and that search key \(x\) is equally probable to be in cach of the array slots.
Let \(S\) and \(T\) be two arrays of \(m\) and \(n\) elements, respectively. Write an algorithm that finds all the common elements and stores them in an array \(U\) Show that this can be done in \(\Theta(n+m)\) time.
Write an algorithm that deletes a node from a binary search tree considering all possible cases. Analyze your algorithm, and show the results using order notation.
