#include

using namespace std;

int isa(char c)

return ('A' <= c&&c <= 'Z')||('a' <= c&&c <= 'z');

}

int main()

{

char w[10000];//设输入最长不超过10000个字符

intc[51] = { 0 };//设最长的词不超过50个字母

int curl = 0;

int i, s = 0,t=0;

cin.getline(w, 10000);

for (i = 0; i

{

if (isa(w[i] ))

{

curl++;

}

else

{

c[curl]++;

curl = 0;

}

}

for (i = 1; i <= 50; i++)

{

if (c[i])

{

s += i*c[i];

t += c[i];

cout << '(' << i<}

}

cout << s < return 0;
