n, k = map(int, input().split())
s = input()

def chan(s, n, k):  #将字符串s转换成二维数组形式
    a = [[] for i in range(k)]
    b = []
    p = 0; i = 0 
    while p < len(s):
        if s[p] != "-": 
            b.append(s[p])
            p += 1
        else:
            b.append(s[p] + s[p + 1])
            p += 2

        for j in range(n):
            a[i].append(b[i * n + j])
    return a

上面是我瞎说的,流行音乐是多元化的,如果一个"音乐爱好者"能说出上面的话,那ta一定是个"不称职的爱好者".
