区别格式:1)There is a blank line between output blocks. 2)Please output a blank line after each test case.
使用字符串模拟是不行的,要学会想别的方法解决、、、、
#include <iostream>
using namespace std;
long long cnt[50][27];
int main(int argc, char *argv[])
{
int t;
cin >> t;
while(t--)
{
memset(cnt,0,sizeof(cnt));
char s1[31] = " ",s2[31] = " ";
int k;
cin >> s1 >> s2 >> k;
for(int i = 0;i < strlen(s1);i++)
cnt[0][s1[i]-97]++;
for(int i = 0;i < strlen(s2);i++)
cnt[1][s2[i]-97]++;
for(int i = 2;i <= k;i++)
{
for(int j = 0;j < 26;j++)
cnt[i][j] = cnt[i-1][j] + cnt[i-2][j];
}
for(int i = 0;i < 26;i++)
cout << char(97+i) << ":" << cnt[k][i] << "\n";
cout << "\n";//Please output a blank line after each test case.
}
return 0;
}
