Solution
To solve this problem, we need to reverse a subarray based on the given input. Let's break down the steps to find the required output.
Step 1: Read the input values. The given input consists of two lines. The first line represents the value of M, and the second line represents the array elements.
Step 2: Split the array elements. Split the array elements using the space as a delimiter and store them in a list or array.
Step 3: Reverse the subarray. Considering 0-based indexing, we need to reverse the subarray from index M+1 to N-1, where N is the length of the array. In other words, we need to reverse the elements starting from the (M+1)th index up to the last index.
Step 4: Print the output. Print the reversed subarray elements, separated by spaces.
Let's apply these steps to the given sample input:
Sample Input: 26 31 2 3 4 5 65 210 9 8 7 6
Step 1: M = 2, Array = [31, 2, 3, 4, 5, 65, 210, 9, 8, 7, 6]
Step 2: Split the array elements: [31, 2, 3, 4, 5, 65, 210, 9, 8, 7, 6]
Step 3: Reverse the subarray from index M+1 to N-1: Subarray = [3, 4, 5, 65, 210, 9, 8, 7, 6] Reversed subarray = [6, 7, 8, 9, 210, 65, 5, 4, 3]
Step 4: Print the output: 6 7 8 9 210 65 5 4 3
Therefore, the required output for Sample Input 1 is 6 7 8 9 210 65 5 4 3.
Let's apply the same steps to the second sample input:
Sample Input: 27 31 4 5 6 6 7 7 9 310 4 5 2 3 6 1 3 6
Step 1: M = 3, Array = [31, 4, 5, 6, 6, 7, 7, 9, 3, 10, 4, 5, 2, 3, 6, 1, 3, 6]
Step 2: Split the array elements: [31, 4, 5, 6, 6, 7, 7, 9, 3, 10, 4, 5, 2, 3, 6, 1, 3, 6]
Step 3: Reverse the subarray from index M+1 to N-1: Subarray = [6, 7, 9, 3, 10, 4, 5, 2, 3, 6, 1, 3, 6] Reversed subarray = [6, 3, 1, 6, 3, 2, 5, 4, 10, 3, 9, 7, 7, 6]
Step 4: Print the output

You are given a 0-indexed integer array nums. A subarray s of length m is called alternating if:m is greater than 1.s1 = s0 + 1.The 0-indexed subarray s looks like [s0, s1, s0, s1,...,s(m-1) % 2]. In other words, s1 - s0 = 1, s2 - s1 = -1, s3 - s2 = 1, s4 - s3 = -1, and so on up to s[m - 1] - s[m - 2] = (-1)m.Return the maximum length of all alternating subarrays present in nums or -1 if no such subarray exists.A subarray is a contiguous non-empty sequence of elements within an array. Example 1:Input: nums = [2,3,4,3,4]Output: 4Explanation: The alternating subarrays are [3,4], [3,4,3], and [3,4,3,4]. The longest of these is [3,4,3,4], which is of length 4.Example 2:Input: nums = [4,5,6]Output: 2Explanation: [4,5] and [5,6] are the only two alternating subarrays. They are both of length 2.
You are given two 0-indexed integer arrays nums1 and nums2 of sizes n and m, respectively.Consider calculating the following values:The number of indices i such that 0 <= i < n and nums1[i] occurs at least once in nums2.The number of indices i such that 0 <= i < m and nums2[i] occurs at least once in nums1.Return an integer array answer of size 2 containing the two values in the above order.
