You are given an integer array nums.

An element nums[i] is considered valid if it satisfies at least one of the following conditions:

• It is the first element or the last element of the array.

• nums[i] is strictly greater than every element to its left.

• nums[i] is strictly greater than every element to its right.

Return an array containing all valid elements in the order they appear in nums.

Constraints:

• $1 \leq$ nums.length $\leq 100$

• $1 \leq$ nums[i] $\leq 100$
