    #import regex package --> iterate through input, use regex "^[789]\d{9}$" to match to input using findall --> finall returns a list, if list size is not 0 then a match has been found, and print according result

import re

for i in range(int(input())):
    num = input()
    x = re.findall("^[789]\d{9}$", num)
    
    if len(x) > 0:
        print("YES")
    else:
        print("NO")
