题目很难看懂，大意就是计算每次总得空格数，以及获得每行最小的空格数，输出sum - min*linNum。
AC代码：
注意第11行getchar()。后面scanf("%c”，&ch)的话会先获得换行符。
#include<stdio.h>
int main(){
int n;
int i;
int min = , sum,tmp;
char ch;
while(scanf("%d",&n) != EOF){
printf("n:%d\n",n);
if(n == ) break;
getchar();
sum = ; min = ;
for(i = ; i < n;i++){
tmp = ;
while(){
scanf("%c",&ch);
17
if(ch == ' '){
tmp++;
sum++;
}
else if(ch == '\n')
break;
}
min = min > tmp ? tmp:min;
}
printf("%d\n",(sum - min*n));
}
return ;
}
