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 $s$ of length $n$, consisting of digits.

In one operation you can delete any character from string $s$. 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 $s$ becomes a telephone number.

Input

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

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

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

Output

For each test print one line.

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

Otherwise, print NO.

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