ゲーム開始

game = NumberGuessingGame.new
game.start
機能概要
難易度選択: プレイヤーはeasy, medium, hardのいずれかの難易度を選択でき、難易度によって予想する数の範囲が変わります。

easy: 1-100
medium: 1-500
hard: 1-1000
プレイ統計の表示: プレイしたゲーム数、総試行回数、平均試行回数を表示します。

再プレイ機能: プレイヤーはゲーム終了後、再度プレイするかどうかを選択できます。

実行方法
上記のコードをファイル（例: number_guessing_game_extended.rb）として保存します。
ターミナル（コマンドプロンプト）を開き、そのファイルがあるディレクトリに移動します。
以下のコマンドを実行してゲームを開始します。
bash
ruby number_guessing_game_extended.rb
この拡張版では、より多くの機能を楽しむことができ、プレイヤーは複数回のゲームプレイを通じて自分のパフォーマンスを追跡することができます。
