Problem Statement

Given are two strings S and T.

Let us change some of the characters in S so that T will be a substring of S.

At least how many characters do we need to change?

Here, a substring is a consecutive subsequence. For example, xxx is a substring of yxxxy, but not a substring of xxyxx.

Constraints

The lengths of S and T are each at least 1 and at most 1000.

The length of T is at most that of S.

S and T consist of lowercase English letters.

Input

Input is given from Standard Input in the following format:

S
T

Output

Print the minimum number of characters in S that need to be changed.

Sample Input 1

cabacc
abc

Sample Output 1

1

For example, changing the fourth character a in S to c will match the second through fourth characters in S to T.

Since S itself does not have T as its substring, this number of changes - one - is the minimum needed.

Sample Input 2

codeforces
atcoder

Sample Output 2

6

Solution in C (GCC 9.2.1) (judge verdict: Wrong Answer)

#include<stdio.h>
#include<string.h>

int main(void){
  char* s;
  char* t;
  int count=0;
  int max = 0;

  scanf("%s",s);
  scanf("%s",t);

  for(int i=0;i<=sizeof(s)-sizeof(t);i++){
    for(int j=0;j<sizeof(t);j++){
      if(s[i+j]==t[j]) count++;
    }
    if(count >= max) max = count;
    count = 0;
  }

  printf("%d",sizeof(t)-max);

  
  /*scanf("%d%d%d",&d,&t,&s);
  if(s*t >= d) printf("Yes");
  else printf("No");*/
  return 0;
}
