Solution

	#include <iostream>
	#include <cstdlib>
	#include <string>
	using namespace std;
	int main(int argc, char** argv) {
	string s;
	cin>>s;
	int i=0;
	int c[10]={0,0,0,0,0,0,0,0,0};
	while(s[i]!='\0')
	{
	switch(s[i])
	{
	case 48:c[0]++;i++;break;
	case 49:c[1]++;i++;break;
	case 50:c[2]++;i++;break;
	case 51:c[3]++;i++;break;
	case 52:c[4]++;i++;break;
	case 53:c[5]++;i++;break;
	case 54:c[6]++;i++;break;
	case 55:c[7]++;i++;break;
	case 56:c[8]++;i++;break;
	case 57:c[9]++;i++;break;
	}
	}
	// print count of each digit
	for(int j=0;j<=9;j++)
	{
	cout<<j<<" "<<c[j]<<endl;
	} return 0;
	}
