Solution: Number of Valid Subarrays
Explore how to count non-empty contiguous subarrays where the first element is less than or equal to all others using a monotonic increasing stack. This lesson guides you through implementing a linear time complexity algorithm in C++ that processes the array efficiently by pushing and popping indices. Understand how amortized analysis ensures optimal performance and learn to manage tradeoffs in space and 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:
nums.length...
