#include<iostream>
#include<cstring>
using namespace std;
string s;
int len;
int c[26];
void menset ()
{
for (int i = 0;i <= 25;i++)
{
c[i] = 0;
}
}
void scan ()
{
cin >> s;
len = s.size();
}
void cntp ()
{
for (int i = 0;i <= len - 1;i++){
c[s[i] - 'a']++;
}
}
bool check (int i)
{
return c[i] == 0;
}
void print ()
{
for (int i = 0;i <= 25;i++){
if (! check(i))
{
char k;
k = 'a' + i;
cout << k << ":" << c[i] << "\n";
}
}
}
int main(){
menset();
scan();
cntp();
print();
}
这里空空如也
