Continuous Subarray Sum
Given an integer array nums and an integer k, return true if nums has a good subarray or false otherwise.
Given an integer array nums and an integer k, return true if nums has a good subarray or false otherwise.
A good subarray is a subarray where:
Note that:
Example 1
Input: nums = [23,2,4,6,7], k = 6
Output: true
Explanation: [2, 4] is a continuous subarray of size 2 whose elements sum up to 6.
Example 2
Input: nums = [23,2,6,4,7], k = 6
Output: true
Explanation: [23, 2, 6, 4, 7] is an continuous subarray of size 5 whose elements sum up to 42. 42 is a multiple of 6 because 42 = 7 * 6 and 7 is an integer.
Example 3
Input: nums = [23,2,6,4,7], k = 13
Output: false
Constraints
- 1 <= nums.length <= 10^5
- 0 <= nums[i] <= 10^9
- 0 <= sum(nums[i]) <= 231 - 1
- 1 <= k <= 231 - 1
