standard output

Dreamoon has a string s and a pattern string p. He
first removes exactly x characters from s obtaining
string s' as a result. Then he calculates  that
is defined as the maximal number of non-overlapping substrings equal to p that can be found in s'.
He wants to make this number as big as possible.

More formally, let's define  as
maximum value of  over
all s' that can be obtained by removing exactly x characters
froms. Dreamoon wants to know  for
all x from 0 to |s| where |s| denotes
the length of string s.

Input

The first line of the input contains the string s (1 ≤ |s| ≤ 2 000).

The second line of the input contains the string p (1 ≤ |p| ≤ 500).

Both strings will only consist of lower case English letters.

Output

Print |s| + 1 space-separated integers in a single line representing the  for
all x from 0 to |s|.

题意：RT

思路：dp[i][j]表示s的前i个字符一共匹配了j个p串，删掉的最少字符数

            先用一个数组en[i]预处理出在s串的每一个位置i。直到能最早匹配p串的结束的位置

            转移为dp[ en[i+1] ][j+1]= min (dp[ en[i+1] ][j+1] 。dp[ i ][j] + (en[i+1]-i-m) )
