Solution: Number of Valid Subarrays
Understand how to count valid contiguous subarrays where the start element is the smallest or equal within the subarray by employing a monotonic increasing stack. This lesson guides you through an O(n) algorithm to efficiently solve the problem, explaining stack operations and amortized time complexity.

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:
