Solution: Count Subarrays With Fixed Bounds
Explore how to efficiently count fixed-bound subarrays using the two-pointers technique. Understand how to track positions of minK, maxK, and invalid elements to identify valid subarrays in a single pass, optimizing both time and space complexity.

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.
