Teaching Kids Programming: Videos on Data Structures and Algorithms You are given a binary array nums. We call a subarray alternating if no two adjacent elements in the subarray have the same value. Return the number of alternating subarrays in nums. Example 1: Input: nums = Output: 5 Explanation: The following subarrays are alternating: , , , , and . Example 2: Input: nums = Output: 10 Explanation: Every subarray of the array is alternating. There are 10 possible subarrays that we can choose. Constraints: 1 <= nums.length <= 10^5 nums is either 0 or 1. Hints: Try Continue Reading »
