Solution: Number of Valid Subarrays
Understand how to count subarrays whose first element is the smallest by applying a monotonic increasing stack approach. Learn to traverse the array while managing a stack to efficiently enumerate valid subarrays in linear time with optimal space. This lesson helps you grasp the solution to a common algorithmic problem useful for coding interviews.

Statement
Given an integer array nums, count how many non-empty contiguous subarrays exist where the first element of each subarray is less than or equal to every other element within that subarray.
Note: A subarray is defined as a contiguous portion of an array.
Constraints:
