Solution: Create Maximum Number
Explore how to build the lexicographically largest number of length k by merging digits from two arrays. Understand splitting digits between arrays, selecting the strongest subarrays via a greedy stack approach, and merging them with two pointers and suffix comparisons. This lesson teaches the practical use of two pointers and monotonic stacks to solve complex digit sequence problems efficiently.
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 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.
