请教这道题如何解决输入length=0的字符串/*****************************
一下是我写的代码,测试了几组数组,是对的,但是总是wa,希望哪位帮我看看!!!!
谢谢!!
我的程序不能输入length=0的字符串,是不是这格问题??????????
*****************************/
#include<iostream>
#include<cstring>
using namespace std;
int main()
{
long n;
char str1[46],str2[46];
cin>>n;
long p=0;
while(n--)
{
p++;
int i,j,k=0,t=0,len1=0,len2=0;
scanf("%s",str1); //不知道这里输入的时候是否有问题
scanf("%s",str2);
len1=strlen(str1);
len2=strlen(str2);
if(len1==0||len2==0)
{
if(len1>len2)
cout<<"Case #"<<p<<": "<<len1<<endl;
else
cout<<"Case #"<<p<<": "<<len2<<endl;
continue;
}
for(i=0;i<len1;i++)
{
for(j=0;j<len2;j++)
{
if(str1[i]==str2[j])
{
str2[j]='0';
k++;
break;
}
}
if(k==len2)
break;
}
t=len1+len2-2*k;
cout<<"Case #"<<p<<": "<<t<<endl;
}
return 0;
}
