Study it. Good luck.

Probably you should use data structure with quick search, like python set/dictionary.

https://docs.python.org/3/tutorial/datastructures.html

There is "Time limit exceeded" with binary search too.

i think that on python i wil not can solve this

import sys
ll = set()
for i in range(int(sys.stdin.readline())):
    ll.add(sys.stdin.readline())
n = 0
for j in range(int(sys.stdin.readline())):
    if sys.stdin.readline() in ll:
        n += 1
print(n)
