Asked in companies
You’re given an array 'arr' of size 'n' and an integer 'k'.
Your task is to split 'arr' into 'k' sub-arrays such that the maximum sum achieved from the 'k' subarrays formed must be the minimum possible.
A subarray is a contiguous part of the array.
Return the minimum possible value of the maximum sum obtained after splitting the array into 'k' partitions.
Example:
Input: ‘arr’ = [1, 1, 2] and ‘k’ = 2
Output: 2
Explanation: If we want to make two subarrays, there are two possibilities: [[1], [1, 2]] and [[1, 1], [2]]. We can see that the maximum sum of any subarray is minimized in the second case. Hence, the answer is 2, which is the maximum sum of any subarray in [[1, 1], [2]].

You are given a 2-dimensional array/list having N rows and M columns, which is filled with ones(1) and zeroes(0). 1 signifies land, and 0 signifies water.
A cell is said to be connected to another cell, if one cell lies immediately next to the other cell, in any of the eight directions (two vertical, two horizontal, and four diagonals).
A group of connected cells having value 1 is called an island. Your task is to find the number of such islands present in the matrix.
