额，这个用到啥了？好像只有字符串以'\0'为结尾吧...

code:

#include<cstdio>
char str[100001] ;
char substr[100001] ;
int main(){
    int i, j ;
    while(~scanf("%s%s", substr, str)){
        i = 0, j = 0 ;
        while(substr[i]!='\0'&&str[j]!='\0'){
            if(substr[i]==str[j])
                i ++ ;
            j ++ ;
        }
        if(substr[i]=='\0')
            printf("Yes\n") ;
        else
            printf("No\n") ;
    }

}
