Solution: Count Subarrays With Fixed Bounds
Explore how to solve the fixed-bound subarray counting problem using the two-pointer technique. Understand how to track indices of minK, maxK, and invalid numbers to count valid subarrays in one pass. This lesson helps you improve problem-solving efficiency and grasp key algorithmic thinking for 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.
