The next greater element of some element x in an array is the first greater element that is to its right in the same array.
You are given two distinct 0-indexed integer arrays nums1 and nums2, where nums1 is a subset of nums2.
For each element nums1[i], find the index j such that nums2[j] == nums1[i] and determine the next greater element of nums2[j] in nums2. If there is no next greater element, then the answer for this query is -1.
Example 1:
Input: 4 1 2 1 3 4 2 Output: -1 3 -1
Example 2:
Input: 2 4 1 2 3 4 Output: 3 -1
Input format: First line: nums1. Second line: nums2.
Output format: Space-separated next greater elements.
