第一题：输出元素个数统计，AC100%

n,m = [int(i) for i in input().split(" ")]
A = [int(i) for i in input().split(" ")]
A = sorted(A)
query  = []
for _ in range(m):
    query.append(int(input()))
m = {}.fromkeys(query)
for key in m.keys():
    m[key] = 0
for i in range(len(A)):
    if A[i]  in m:
        m[A[i]] += 1
for k in query:
    print(m[k])
n,m = [int(i) for i in input
