Solution: Continuous Subarray Sum
Explore how to identify a continuous subarray with a sum multiple of k by using hash maps to track cumulative sum remainders. Understand the approach to solve this problem with O(n) time complexity and apply it confidently in coding interviews.

Statement
Given an integer array nums and an integer k, determine if nums contains a good subarray. Return true if such a subarray exists; otherwise, return false.
A subarray of nums is considered good if:
Its length is at least
. The sum of its elements is a multiple of
k.
Notes:
A subarray is defined as a contiguous sequence of elements within an array.
An integer
xis a multiple ofkif there exists an integernsuch thatx = n * k. Note that0is always considered a multiple ofk.
