Solution: Subarrays with K Different Integers
Understand the sliding window technique to efficiently find the number of subarrays containing exactly k distinct integers. This lesson guides you through using two pointers and frequency maps to implement a linear time solution that balances expanding and shrinking windows to maintain the desired distinct 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
