諺語

說明

俗話說，少了一根馬蹄釘，就失去了一個王國。

給定一個輸入陣列，產生對應的諺語。 例如，給定["nail", "shoe", "horse", "rider", "message", "battle", "kingdom"]這個陣列，你要輸出這首諺語的完整內容：

For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.
And all for the want of a nail.

注意，輸入的陣列可能不同；你的解法應該要能處理任意長度與內容的陣列。 輸出的文字中，不該有任何一行是固定不變的字串；每一行都應該隨著給定的輸入而變化。

實作

如果陣列中的最後一個元素是object而不是string，它會帶有一個修飾詞，用來修改這句諺語的最後一行。

proverb('nail', 'shoe', { qualifier: 'horseshoe' });
// => For want of a nail the shoe was lost.
//    And all for the want of a horseshoe nail.
