You scan through a list of n elements, keeping track of the max. Every time you encounter a new max, you update some variable. How many times do you expect to make such an update?

Define the answer as a random variable, break it into indicator random variables, use linearity of expectation, evaluate each IRV, and finally express the answer as best you can using O, Ω, or Θ.

Find the last node of a linked list of n elements whose index is a multiple of k (counted from 0). For example, if the list is 12 → 75 → 37 → 99 → 12 → 38 → 99 → 60 ↓ and k = 4, then you should return the second 12 (with index 4). Your algorithm should take O(n) time and use O(1) extra space. Implement the following method in LinkedList.java. public T lastK(int k) LinkedList.java. public...
