Next Greater Element I
You are given two arrays(without duplicates)nums1
andnums2
wherenums1
’s elements are subset ofnums2
. Find all the next greater numbers fornums1
's elements in the corresponding places ofnums2
.
The Next Greater Number of a numberxinnums1
is the first greater number to its right innums2
. If it does not exist, output -1 for this number.
Example 1:
Input: nums1 = [4,1,2], nums2 = [1,3,4,2].
Output: [-1,3,-1]
Explanation:
For number 4 in the first array, you cannot find the next greater number for it in the second array, so output -1.
For number 1 in the first array, the next greater number for it in the second array is 3.
For number 2 in the first array, there is no next greater number for it in the second array, so output -1.
Example 2:
Input: nums1 = [2,4], nums2 = [1,2,3,4].
Output: [3,-1]
Explanation:
For number 2 in the first array, the next greater number for it in the second array is 3.
For number 4 in the first array, there is no next greater number for it in the second array, so output -1.
Note:
All elements in
nums1
andnums2
are unique.The length of both
nums1
andnums2
would not exceed 1000.
Solution
class Solution {
public int[] nextGreaterElement(int[] nums1, int[] nums2) {
}
}
