Solution: Count Subarrays With Fixed Bounds
Understand how to count the number of fixed-bound subarrays within an array by implementing a single-pass two-pointer solution. This lesson helps you track positions of key elements to efficiently identify valid subarrays without redundant checks. By the end, you'll be able to apply this approach to similar coding interview challenges involving linear data structures and range constraints.
We'll cover the following...
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.
Constraints:
