Many languages have a multi-line string. Old Java needs \n and plus signs for every line.

Same code works in Java810172125Basic features only, so nothing changes between versions.
/*
 * Problem : Process one line of text.
 * Input   : One line of text.
 * Output  : A 4 line card.
 * Approach: Join lines or use a multi-line literal.
 * Time    : O(n)

 * Java    : 8 or newer.

public class Main {
    // This method solves the task. It receives the input and returns the answer.
    static String solve(String s) {
        // Step 1: Join the lines with \n. Quotes and plus signs make the code hard to read.
        String name = s.trim();
        return "+----------+\n"
