Solution: Number of Valid Subarrays
Explore how to count non-empty contiguous subarrays in an integer array where the first element is less or equal to all others. Learn to implement a monotonic increasing stack solution with linear time and space complexity. This lesson helps you understand stack operations, amortized analysis, and application of stacks in coding interview problems.

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.
