( 637 ) H Holiday Wall Ornaments PROGRAMMING strings

B"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 a of length n . His favorite nephew has another binary string b of length m ( m <= q n ). Mr. Chanek's nephew loves the non-negative integer k . His nephew wants exactly k occurrences of b as substrings in a . However, Mr. Chanek does not know the value of k . So, for each k ( 0 <= q k <= q n - m + 1 ), find the minimum number of elements in a that have to be changed such that there are exactly k occurrences of b in a . A string s occurs exactly k times in t if there are exactly k different pairs (p,q) such that we can obtain s by deleting p characters from the beginning and q characters from the end of t . The first line contains two integers n and m ( 1 <= q m <= q n <= q 500 ) -- size of the binary string a and b respectively. The second line contains a binary string a of length n . The third line contains a binary string b of length m . Output n - m + 2 integers -- the (k+1) -th integer denotes the minimal number of elements in a that have to be changed so there are exactly k occurrences of b as a substring in a . For k = 0 , to make the string a have no occurrence of 101, you can do one character change as follows. 100101011 rightarrow 100100011 For k = 1 , you can also change a single character. 100101011 rightarrow 100001011 For k = 2 , no changes are needed.
