Solution: Number of Valid Subarrays
Explore how to count valid subarrays where the first element is less than or equal to others by using a monotonic increasing stack. Understand the algorithm's logic, amortized linear time complexity, and apply stack operations to solve this common coding interview problem.

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:
