Solution: Count Subarrays With Fixed Bounds

Explore how to count fixed-bound subarrays within an integer array by leveraging the two pointers approach. Understand the method to track boundary indices and invalid elements to calculate the number of valid subarrays in one pass, improving time efficiency in coding interviews.

We'll cover the following...

Statement

Given an integer array, nums, and two integers minK and maxK, return the number of fixed-bound subarrays.

A subarray in nums is called a fixed-bound subarray if it satisfies the following conditions:

  1. The smallest value in the subarray equals minK.

  2. The largest value in the subarray equals maxK.

Note: A subarray is a contiguous sequence of elements within an array.
