help!!!!! 真的假的这代码过不去吗???????????????????#include <stdio.h> #include <string.h> #define N 100 int lcs_len(char *a,char *b, int c[][N]) { int m=strlen(a),n=strlen(b),i,j; for(i=0;i<=m;i++) c[i][0]=0; for(j=0;j<=n;j++) c[0][j]=0; for(i=1;i<=m;i++) for(j=1;j<=n;j++) { if (a[i-1]==b[j-1]) c[i][j]=c[i-1][j-1]+1; else if(c[i-1][j]>=c[i][j-1]) c[i][j]=c[i-1][j]; else c[i][j]=c[i][j-1]; } return c[m][n]; } int build_lcs(char *s,char *a,char *b) { int k,i=strlen(a),j=strlen(b),c[N][N]; k=lcs_len(a,b,c); s[k]='\0'; while(k>0) if(c[i][j]==c[i-1][j]) i--; else if(c[i][j]==c[i][j-1]) j--; else { s[--k]=a[i-1]; i--; j--; } return strlen(s); } void main() { int i,n; char a[N],b[N],str[N]; scanf("%d",&n); scanf("%s",a); scanf("%d",&n); scanf("%s",b); printf("%d\n",strlen(b)-build_lcs(str,a,b)); } Followed by:
