Solution: Count Subarrays With Fixed Bounds
Explore how to count fixed-bound subarrays in an integer array by applying the two pointers method. Understand tracking key indices and efficiently compute valid subarrays without using brute force. This lesson helps you implement a single-pass algorithm with O(n) time complexity and O(1) space to solve this common coding interview pattern.

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:
The smallest value in the subarray equals
minK.The largest value in the subarray equals
maxK.
Note: A subarray is a contiguous sequence of elements within an array.
