Solution: Create Maximum Number

Explore how to form the maximum possible number of length k by selecting digits from two arrays using the two pointers pattern. Understand how to split digit selection, pick the strongest subarrays, and merge them optimally with tie-breaking based on lexicographic order. This lesson guides you through the step-by-step solution and complexity analysis to solve this problem efficiently in JavaScript.

We'll cover the following...

Statement

You are given two integer arrays, nums1 and nums2, of lengths m and n, respectively. Each array represents the digits of a number.

You are also given an integer k. Create the largest possible number of length k (where k ≤\leq m ++ n) using digits from both arrays. You may interleave digits from the two arrays, but the relative order of digits within the same array must be preserved.

Return an array of k digits representing the maximum number.

Constraints:

  • m == nums1.length

  • n == nums2.length

  • 1≤1 \leq m, n ...
