这样子居然AC了……没想到string.push_back(int)会把int转成ASC2码然后给我输出一堆乱码…… 最后又建了一个数组……
//3438 Look and Say
#include<iostream>
#include<string>
using namespace std;
void getElem(string list)
{
int presentNum=list[0];
int S[1001]={0};
int sum=0;
int j=0;
string res;
for(int i=0;i<list.length();i++)
{
//cout<<list[i]<<endl;
if(list[i]==presentNum) ++sum;
else
{
S[j]=sum;
++j;
//res+=sum;
res.push_back(presentNum);
presentNum=list[i];
sum=1;
}
}
for(int k=0;k<res.length();k++)
{
cout<<S[k]<<res[k]; //傻死了……T_T
}
cout<<endl;
}
int main()
{
int n,i=0;
cin>>n;
while(i!=n)
{
string str;
cin>>str;
str.push_back(1); //结束标记
getElem(str);
++i;
}
system("pause");
return 0;
}
