English:

Here at the Concerned Citizens of Commerce (CCC), we have noted that telemarketers like to use seven-digit phone numbers where the last four digits have three properties. 

Looking just at the last four digits, these properties are:

• the first of these four digits is an 8 or 9;
• the last digit is an 8 or 9;
• the second and third digits are the same.

For example, if the last four digits of the telephone number are 8229, 8338, or 9008, these are telemarketer numbers.

Write a program to decide if a telephone number is a telemarketer number or not, based on the last four digits. 

If the number is not a telemarketer number, we should answer the phone, and otherwise, we should ignore it.

在这里，在 Concerned Citizens of Commerce（CCC）中，我们注意到电话推销员喜欢使用七位数的电话号码，而后四位数具有三个属性。
仅查看最后四个数字，这些属性是：

• 这四个数字中的第一个数字是8或9；
• 最后一位是8或9；
• 第二和第三位数字相同。
