Number of Valid Subarrays

Explore how to efficiently count valid subarrays that meet specific ordering criteria by applying stack data structures. Understand the problem constraints and implement a solution in C#, improving your ability to solve similar array and stack coding challenges for 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:

  • 11 \leq ...
