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