Solution: Count Subarrays With Fixed Bounds

Explore how to identify and count fixed-bound subarrays in an integer array using the two pointers technique. This lesson helps you develop an efficient one-pass solution that tracks key positions to solve the problem with optimal time and space complexity, perfect 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:

  1. The smallest value in the subarray equals minK.

  2. The largest value in the subarray equals maxK.

Note: A subarray is a contiguous sequence of elements within an array.

Constraints:

  • 2 ...
