#include<iostream>
using namespace std;int main()
{unsigned scores[11] = {};unsigned grade;while (cin >> grade){if (grade <= 100)++(scores[grade / 10]);}for (int i = 0; i <= 10; ++i) {if (i != 10) {cout << i * 10 << "~" << i * 10 + 9 << ':'<< endl;cout << scores[i] << endl;}else{cout << 100 << ':'<< endl;cout << scores[i] << endl;}}return 0;
