1. Given a array of integers find the index which partitions the array to two with high numbers and low numbers. For example [5, -1, 3, 8,6] the index 3 will partition the array to [5,-1,3] and [8,6] all the numbers in the second partition are greater than first. The solution has to work in O(n).
Given two integer arrays. Find the Largest Common sub array. For example, arr1 = {1,2,3,2,3,2} arr2={2,2,3,3,4,5}, the largest common sub array is {2,2,3,3}
