You are given an integer array nums.
An element nums[i] is considered valid if it satisfies at least one of the following conditions:
The first and last elements are always valid.
Return an array of all valid elements in the same order as they appear in nums.
Example 1:
Input: nums = [1,2,4,2,3,2]
Output: [1,2,4,3,2]
Explanation:
nums[0] and nums[5] are always valid.nums[1] and nums[2] are strictly greater than every element to their left.nums[4] is strictly greater than every element to its right.[1, 2, 4, 3, 2].Example 2:
Input: nums = [5,5,5,5]
Output: [5,5]
Explanation:
[5, 5].Example 3:
Input: nums = [1]
Output: [1]
Explanation:
Since there is only one element, it is always valid. Thus, the answer is [1].
Constraints:
1 <= nums.length <= 1001 <= nums[i] <= 100Loading editor...
