Next Greater Element
Try to solve the Next Greater Element I problem.
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, x, in an array is the first greater element present on the right side of x in the same array. However, in the context of this problem, for each element x in nums1
, find the next greater element present on the right side of x in nums2
and store it in the ans
array. If there is no such element, store −1 for this number. The ans
array should be of the same length as nums1
, and the order of the elements in the ans
array should correspond to the order of the elements in nums1
.
Return the ans
array after finding the next greater elements.
Note: The input data may or may not be sorted.
