zoj 2886 Look and Say

//這一題和2478差不多，只不過是字串變長了，如果用cout頻繁輸出的情況下就會逾時！所以用printf！#include "iostream"#include "string"#include "stdio.h"using namespace std;int main(){int TestCase;cin >> TestCase;while (TestCase--){string str;char first;int length, count = 0;cin >> str;length = str.size();first = str[0];for (int i = 0; i < length; i++){if (str[i] == first){count++;if (i == length - 1)printf("%d%c", count, first);}else{printf("%d%c", count, first);first = str[i];count = 1;if (i == length - 1)printf("%d%c", count, first);}}cout << endl;}}
