Solution: Create Maximum Number
Explore how to form the maximum number of specified length by combining digits from two arrays while preserving their order. Learn to apply the two-pointers method and a greedy stack approach. Understand how to split digits optimally, select the largest subsequences, and merge them by comparing suffixes for the lexicographically greatest outcome.
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.
