請依照註解的要求完成這段程式碼:
```js=
let ProductInfo = {
Price: 1000, // 購買價格
coupons:[

due_date: "2021-10-15",
id: 123,
is_enabled: 0,
percent: 0.7,
title: "特惠七折",
},
{
due_date: "2021-08-08",
id: 456,
is_enabled: 1,
percent: 0.5, // 折扣比例
title: "特惠五折",
}
]
}
/* 請取得 coupons 陣列中 id 為 456 的 percent，並賦值給 discountPercent */
let discountPercent;
/* 請取得 coupons 陣列中 id 為 456 的 title，並賦值給 title */
let title;
/* 請取得 coupons 陣列中 id 為 456 的 is_enabled，並填入以下 if 判斷式中;
如果判斷為 true，則對「購買價格」進行折扣*/
if(/* 程式碼撰寫處 */){
/* 程式碼撰寫處，對「購買價格」進行折扣*/
console.log(`優惠券已啟用，${title}`);
}else {
console.log("優惠券未啟用");
}
console.log(`購買價格 ${ProductInfo.Price}`);
