Solution: Kth Smallest Product of Two Sorted Arrays
Discover how to efficiently find the kth smallest product of two sorted integer arrays by applying a modified binary search on the answer space. Understand handling positive, negative, and zero values and learn how to count valid products within constraints to solve the problem with optimal time and space complexity.
We'll cover the following...
Statement
You are given two sorted 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
Note: Both
nums1andnums2are sorted in non-decreasing order. The arrays may contain negative numbers and zero, so the products can be negative, zero, or positive.
Constraints:
...
