// Instructions
// For want of a horseshoe nail, a kingdom was lost, or so the saying goes.
// Given a list of inputs, generate the relevant proverb. For example, given the list ["nail", "shoe", "horse", "rider", "message", "battle", "kingdom"], you will output the full text of this proverbial rhyme:
// 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.
// Note that the list of inputs may vary; your solution should be able to handle lists of arbitrary length and content. No line of the output text should be a static, unchanging string; all should vary according to the input given.
