Consider an X x Y array of 1's and 0s. The X axis represents "influences" meaning that X influences Y. So, for example, if $array[3,7] is 1 that means that 3 influences 7. An "influencer" is someone who influences every other person, but is not influenced by any other member. Given such an array, write a function to determine whether or not an "influencer" exists in the array.
assume you are writing number in ascending order to an array of constant size. once you reach the end of the array, you start writing from the beginning, thus writing over the oldest entries. write an algorithm for finding a specific number in this array.
Write a function that divides two numbers without using the divide '/' operator.
Determine whether the binary representation of a number if a palindrome or not, code it on a white board.

Write a function that finds the median of a set of three numbers, also find the Big O. Can it be done with only 2 comparisons, or do you need 3?

Implement a function that takes the set-wise subtraction of two sorted sets of integers. ie A = {1, 2, 3}, B = {3, 4, 5} => A - B = {1, 2}. There can be duplicates, in which case all duplicates should be removed should there be an occurrence in B. IE: {1, 2, 3, 3, 3} - {2, 3} = {1}.
