We'll cover the following...

Statement

Given the two distinct integer arrays, nums1 and nums2, where nums1 is a subset of nums2, find all the next greater elements for nums1 values in the corresponding places of nums2.

In general, the next greater element of an element, xx, in an array is the first greater element present on the right side of xx in the same array. However, in the context of this problem, for each element xx ...
