Answer 1

An array A is greater than an array B if the first non-matching item in both arrays has a greater value in A than in B. For example,

• A = [3, 4, 9, 6, 8]
• B = [3, 4, 8, 6, 7]

A is bigger than B because the first non-matching element is larger in A (A[2] > B[2]).

A contiguous subarray is a subarray that has consecutive indexes.

Given an array arr consisting of n integers and an integer k, return the largest contiguous subarray of length k from all the possible contiguous subarrays of length k.

Constraints

• 1 <= k <= n <= 100
• 1 <= arr[i] <= 1000

Examples

Example 1:

Input:

arr = [1, 4, 3, 2, 5]

k = 4

Output: [4, 3, 2, 5]

Explanation:

There are 2 possible subarrays of size 4: [1, 4, 3, 2] and [4, 3, 2, 5], and the largest subarray is [4, 3, 2, 5].
