What is the time complexity to find the median in an array?
Output a single linked list in reverse, in linear time and constant space, and recursively
Given n+1 buckets with n of them with ball inside and move(a,b) function, that moves ball from bucket a to bucket b. Each ball has a different number from [1,n] on it. Move balls, so each bucket has a ball with matching number in it.
Given 2 arrays sorted in ascending orders (a[n] and b[n*2]) with the second half of array a[] being empty, create a function that merges both arrays into a single sorted array.

Given a root to a binary tree where each node holds an integer. Write a method that returns the sum of all the integers in the tree.
Write a function in Java that will take a sorted array of ints, possibly with duplicates, and compact the array removing all the duplicate numbers. That is, if the contains the numbers - 1, 3, 7, 7, 8, 9, 9, 9, 10, then when the function returns, the contents should be - 1, 3, 7, 8, 9, 10. Be sure your answer is as efficient as possible. Describe the efficiency of your algorithm using big O notation.
