##### Canadian Computing Competition: 2018 Stage 1, Junior #1

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 or ;
• the last digit is an or ;
• 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.

#### Input Specification

The input will be lines where each line contains exactly one digit in the range from to .

#### Output Specification

Output either ignore if the number matches the pattern for a telemarketer number; otherwise, output answer.

#### Sample Input 1

9
6
6
8

#### Sample Output 1

ignore

#### Explanation for Sample Output 1

The first digit is , the last digit is , and the second and third digit are both , so this is a telemarketer number.

#### Sample Input 2

5
6
6
8

#### Sample Output 2

answer

#### Explanation for Sample Output 2

The first digit is , and so this is not a telemarketer number.

So I wanted to see if capitalization counts. It does. Beware, unsuspecting CCC users!

Man spelling counts! Couldn't get this 3 pointer cause I wrote ingore instead of ignore. And i dint realize for the longest time.

I had the same problem, except I was using "Ignore" and "Answer" instead of "ignore" and "answer". Case sensitivity is a killer here.

Misread a part of the question.

I think there is a problem with this problem, the inputs should be switched.

Note that:

ignore is when the first and last digits are either 8 or 9 and the two of the middle are the same, not answer

That may be the problem

Also, you should probably read the question again because your if statements are wrong

Considering that:

1. This was a CCC contest question, so the test datas were checked over
2. There are 300 correct submissions on DMOJ

Perhaps you should check over your code.
