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