如何使两个单词在相交字符处交叉。 （一个垂直，另一个水平）
How to get 2 words to cross at intersecting characters. (One vertically and the other horizontally)

我正在为学校做一项家庭作业，作业状态为“获得两个单词作为输入，并垂直打印一个单词，水平打印一个单词，以便它们相交”。

一个例子：

vertical: coffee
horizontal: suffering
  c
  o
suffering
  f
  e
  e

当我输入咖啡并遭受痛苦时，我将其作为输出：

vertical: coffee
horizontal: suffering
   c
   o
suffering
   f
   f
   e
   e

我的代码如下：

public static void main(String[] args) {

    Scanner kb = new Scanner(System.in);

    System.out.print("vertical: ");
    String vertical = kb.next().toLowerCase();

    System.out.print("horizontal: ");
    String horizontal = kb.next().toLowerCase();

    boolean indexed = true;
    int indexOf = 0;
    StringBuilder spaces = new StringBuilder();

    while (indexed) {
      for (int i = 1; i <= vertical.length()-1; i++) {
        String found = vertical.substring(i - 1, i);
        spaces.append(" ");
        if (horizontal.contains(found)) {
          indexOf = i;
          indexed = false;
          break;
        }
      }
    }

    for (int i = 1; i <= vertical.length(); i++) {
      if (i == indexOf) {
        System.out.println(horizontal);
      }
      System.out.println(spaces + vertical.substring(i - 1, i));
    }
  }
