Solution: Number of Valid Subarrays
Explore how to efficiently count non-empty contiguous subarrays where the first element is less than or equal to all others in the subarray. This lesson demonstrates using a monotonic increasing stack to solve the problem in linear time, helping you understand stack applications and amortized analysis in coding interviews.

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:
