Kth Smallest Product of Two Sorted Arrays

Explore how to calculate the kth smallest product from pairs formed between two sorted arrays using a modified binary search approach. Understand how to apply this technique when arrays include negative, zero, and positive values. This lesson helps you develop an efficient search strategy to solve complex product selection problems commonly asked in coding interviews.

Statement

You are given two sorted 00-indexed integer arrays nums1 and nums2, along with an integer k.

Consider all possible products formed by nums1[i] * nums2[j], where i ranges over all valid indices of nums1 and j ranges over all valid indices of nums2. Return the kthk^{th} ...
