Solution: Subarrays with K Different Integers
Discover how to use the sliding window pattern to count the number of contiguous subarrays containing exactly k distinct integers. This lesson guides you through a linear time approach that leverages the difference between subarrays with at most k and at most k minus one distinct integers, helping you effectively solve related coding interview challenges.

Statement
You are given an integer array nums and an integer k. Your task is to return the number of good subarrays of nums.
A good subarray is a contiguous subarray that contains exactly k distinct integers. For example, in the array
