Solution: Count Subarrays With Fixed Bounds
Explore how to count subarrays within an integer array that have fixed minimum and maximum bounds using a single-pass two pointers approach. This lesson helps you understand tracking key indices to efficiently identify valid subarrays without checking all subarrays, improving time complexity to linear.

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.
