题目描述

A telephone number is a sequence of exactly 11 digits, where the first digit is 8. For example, the sequence 80011223388 is a telephone number, but the sequences 70011223388 and 80000011223388 are not.

You are given a string ss of length nn , consisting of digits.

In one operation you can delete any character from string ss . For example, it is possible to obtain strings 112, 111 or 121 from string 1121.

You need to determine whether there is such a sequence of operations (possibly empty), after which the string ss becomes a telephone number.

输入格式

The first line contains one integer tt ( 1t1001 \le t \le 100 ) — the number of test cases.

The first line of each test case contains one integer nn ( 1n1001 \le n \le 100 ) — the length of string ss .

The second line of each test case contains the string ss ( s=n|s| = n ) consisting of digits.

输出格式

For each test print one line.

If there is a sequence of operations, after which ss becomes a telephone number, print YES.

Otherwise, print NO.

说明/提示

In the first test case you need to delete the first and the third digits. Then the string 7818005553535 becomes 88005553535.
