10816번: 숫자 카드 2

 

from bisect import bisect_left,bisect_right
n = int(input())
num_1 = sorted(list(map(int,input().split())))

m = int(input())
num_2 = list(map(int,input().split()))

answer =[0]*m

def search(array1,array2):
        
    for i in range(len(array2)):
        a = bisect_left(array1,array2[i])
        b = bisect_right(array1,array2[i])
        if a is None or b is None:
            print(0)
        else:
            k=b-a
            print(k)

search(num_1,num_2)

bisect_left , bisect_right 이거 두 개 기억해두자
