Next Greater Element
Try to solve the Next Greater Element 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, , in an array is the first greater element present on the right side of in the same array. However, in the context of this problem, for each element in nums1
, find the next greater element present on the right side of in nums2
and store it in the ans
array. If there is no such element, store 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.
Constraints:
-
nums1.length
nums2.length
-
nums1[i]
,nums2[i]
nums1
have distinct integers.nums2
have distinct integers.- All integers in
nums1
also appear innums2
.
