Solution: Number of Valid Subarrays
Understand how to count non-empty contiguous subarrays where the first element is less than or equal to others by applying a monotonic increasing stack. This lesson explains stack operations and an O(n) solution that processes array elements with amortized constant time per operation, enhancing your ability to solve similar array problems efficiently.

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:
