1 2 3 Task 1 There is a forum that has a limit of K characters per entry. In this task your job is to implement an algorithm for cropping messages that are too long. You are given a message, consisting of English alphabet letters and spaces, that might be longer than the limit. Your algorithm should crop a number of words from the end of the message, keeping in mind that: • it may not crop away part of a word; • the output message may not end with a space; • the output message may not exceed the K-character limit; • the output message should be as long as possible. Java 8 This means that, in some cases, the algorithm may need to crop away the entire message, outputting an empty string. For example, given the text: "Codility We test coders" With K = 14 the algorithm should output: "Codility We" Note that: • the output "Codility We te" would be incorrect, because the original message is cropped through the middle of a word; • the output "Codility We would be incorrect, because it ends with a space; • the output "Codility We test coders" would incorrect, because it exceeds the K-character limit; • the output "Codility" would be incorrect, because it is shorter than the correct output. Write a function class Solution { public String solution (String message, int K); } which, given a message and an integer K, returns the message cropped to no more than K characters, as described above. Examples: 1. Given message = "Codility We test coders" and K = 14, the function should return "Codility We".
