Another side note is regarding the choices ofiandj. The below code would subdivide both arrays using its array sizes as weights. The reason is it might be able to guess the k-th element quicker (as long as the A and B is not differed in an extreme way; ie, all elements in A are ...

We are given two sorted arrays (a and b), which do not necessarily need to have an equal number of elements:In these two arrays, we want to find the kth smallest element. More specifically, we want to find the kth smallest element in the combined and sorted array:...
Given two sorted arrays A, B of size m and n respectively. Find the k-th smallest element in the union of A and B. You can assume that there are no duplicate elements. O(lg m + lg n) solution: 1. Maintaining the invariant
