Given an integer array ‘A’ of size ‘N’ and an integer ‘K'.

Split the array ‘A’ into ‘K’ non-empty subarrays such that the largest sum of any subarray is minimized.

Your task is to return the minimized largest sum of the split.

A subarray is a contiguous part of the array.

Example:

Input: ‘N’ = 5, ‘A’ = [1, 2, 3, 4, 5], ‘K’ = 3

Output: 6

Explanation: There are many ways to split the array ‘A’ into K consecutive subarrays. The best way to do this is to split the array ‘A’ into [1, 2, 3], [4], and [5], where the largest sum among the three subarrays is only 6.

You are given 2 non-empty strings 's1' and 's2' consisting of lowercase English alphabets only.

In one operation you can do either of the following on 's1':

(1) Remove a character from any position in 's1'.

(2) Add a character to any position in 's1'.

Find the minimum number of operations required to convert string 's1' into 's2'.

Example:

Input: 's1' = "abcd", 's2' = "anc"

Output: 3

Explanation:
Here, 's1' = "abcd", 's2' = "anc".
In one operation remove 's1[3]', after this operation 's1' becomes "abc".    
In the second operation remove 's1[1]', after this operation 's1' becomes "ac".
In the third operation add 'n' in 's1[1]', after this operation 's1' becomes "anc".

Hence, the minimum operations required will be 3. It can be shown that there's no way to convert s1 into s2 in less than 3 moves.

You are given an array of n integers and an integer k. Your task is to divide the array into exactly k non-empty, contiguous subarrays (or "parts").

For each subarray, you must calculate its "value". The value of a subarray is defined as:

(sum of its elements) - (its minimum element) + (its maximum element)

The goal is to find a partitioning of the original array into k parts such that the sum of the values of all k parts is maximized.

Return this maximum possible total value.

You are given a directed graph with N nodes (numbered 0 to N-1), where each node has an integer value. You are also given an integer k.

You can start your journey at any node in the graph. From your current node, you can move to any of its neighbors by following a directed edge. Each move takes one step. You are allowed to perform at most k moves.

Each time you visit a node (including your starting node), you collect its value. You are allowed to visit the same node multiple times, and its value is added to your total each time you visit.

Your task is to find the maximum possible total value you can accumulate after a path of at most k moves.

You are given a string S which may contain a mix of uppercase letters, lowercase letters, digits, symbols, and spaces.

Your task is to create a new string that consists of only the digit characters ('0' through '9') from the original string S. The digits in the new string must appear in the same relative order as they did in the original string.

If no digits are present in the input string, your function should return an empty string.
