题目描述

The Winter holiday will be here soon. Mr. Chanek wants to decorate his house's wall with ornaments. The wall can be represented as a binary string aa of length nn. His favorite nephew has another binary string bb of length mm (m≤nm \leq n).

Mr. Chanek's nephew loves the non-negative integer kk. His nephew wants exactly kk occurrences of bb as substrings in aa.

However, Mr. Chanek does not know the value of kk. So, for each kk (0≤k≤n−m+10 \leq k \leq n - m + 1), find the minimum number of elements in aa that have to be changed such that there are exactly kk occurrences of bb in aa.

A string ss occurs exactly kk times in tt if there are exactly kk different pairs (p,q)(p,q) such that we can obtain ss by deleting pp characters from the beginning and qq characters from the end of tt.

寒假即将到来。Chanek 先生想用装饰品来装点自家墙壁。墙壁可表示为一个长度为 nn 的 01 字符串 aa。他最喜爱的侄子拥有另一个长度为 mm(m≤nm \leq n)的 01 字符串 bb。

Chanek 先生的侄子钟爱某个非负整数 kk,他希望字符串 bb 在 aa 中恰好作为子串出现 kk 次。

然而,Chanek 先生并不知道 kk 的具体取值。因此,请对每个 kk(0≤k≤n−m+10 \leq k \leq n - m + 1),求出:为使 bb 在 aa 中恰好出现 kk 次,所需修改 aa 中元素的最小次数。

字符串 ss 在字符串 tt 中恰好出现 kk 次,是指:恰好存在 kk 个不同的数对 (p,q)(p,q),使得从 tt 的开头删去 pp 个字符、结尾删去 qq 个字符后,所得字符串恰好为 ss。

输入格式

The first line contains two integers nn and mm (1≤m≤n≤5001 \leq m \leq n \leq 500) — size of the binary string aa and bb respectively.

The second line contains a binary string aa of length nn.

The third line contains a binary string bb of length mm.

第一行包含两个整数 nn 和 mm(1≤m≤n≤5001 \leq m \leq n \leq 500),分别表示二进制字符串 aa 和 bb 的长度。

第二行包含一个长度为 nn 的二进制字符串 aa。

第三行包含一个长度为 mm 的二进制字符串 bb。

输出格式

Output n−m+2n - m + 2 integers — the (k+1)(k+1)-th integer denotes the minimal number of elements in aa that have to be changed so there are exactly kk occurrences of bb as a substring in aa.

输出 n−m+2n - m + 2 个整数——其中第 (k+1)(k+1) 个整数表示:为使字符串 aa 中恰好出现 kk 次子串 bb,所需修改的 aa 中元素的最少个数。

输入输出样例

  • 输入#1

    9 3
    100101011
    101

    输出#1

    1 1 0 1 6 -1 -1 -1

说明/提示

For k=0k = 0, to make the string aa have no occurrence of 101, you can do one character change as follows.

100101011 →\rightarrow 100100011

For k=1k = 1, you can also change a single character.

100101011 →\rightarrow 100001011

For k=2k = 2, no changes are needed.

当 k=0k = 0 时,为使字符串 aa 不包含子串 101,可进行如下单字符修改:

100101011 →\rightarrow 100100011

当 k=1k = 1 时,同样只需修改一个字符:

100101011 →\rightarrow 100001011

当 k=2k = 2 时,无需任何修改。
