n,m = map(int,input().split())

from collections import defaultdict
d = defaultdict(int)
p = dict()

for i in range(n):
    a,b = input().split()
    d[a] += int(b)

input()
for i in range(m):
    name,x,y = input().split()
    if x == 'order':
        if d[y] > 0:
            if name in p:
                print('no')
                continue
            d[y] -= 1
            p[name] = (x,y)
            print('yes')
            continue
        else:
