Solution: Subarrays with K Different Integers
Explore the sliding window technique to count subarrays with exactly k distinct integers in an integer array. Understand how to use two pointers and a frequency map to efficiently solve the problem in linear time. This lesson helps you grasp the method of subtracting subarrays with at most k - 1 distinct integers from those with at most k distinct integers to find the exact count.

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
