Solution: Count Subarrays With Fixed Bounds
Explore how to efficiently count subarrays with fixed minimum and maximum values using a two-pointer technique. Learn to track key positions and avoid invalid subarrays to achieve a linear time complexity solution. This lesson helps you understand and implement an optimal method for fixed-bound subarray problems encountered in coding interviews.

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.
