Solution: Create Maximum Number

Explore how to apply the two pointers technique to create the lexicographically largest number of a given length k by intelligently selecting and merging subarrays from two digit arrays. Learn to optimize splits, use a monotonic stack to pick max subsequences, compare suffixes for tie-breaking, and merge results efficiently. This lesson develops your skills to solve related coding problems with controlled time and space complexity.

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

  • 11 \leq m, n ...
