![Valid Mountain Array
Given an array of integers arr, return true if
and only if it is a valid mountain array.
Recall that arr is a mountain array if and only
if:
arr.length >= 3
There exists some i with 0 <i<arr.length - 1
such that:
arr[0] < arr[1] < ... < arr[i - 1] < arr[i]
arr[i] > arr[i + 1] > ... > arr[arr.length - 1]
Example 1:
Input: arr = [2,1]
Output: false
Example 2:
Input: arr = [3,5,5]
Output: false](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3ff03e3c-2f19-4ffd-874e-3a501cc34229%2Fe48d72e0-e749-40f3-be37-28ad90f94dd2%2F581kbgk_processed.jpeg&w=3840&q=75)
