// Read in a list of grades in the range 0..100, preceded

// by the number of grades, and

// print out how many times each grade appears

public static void main (String arg[]) {

TokenReader in = new TokenReader(System.in);

int n= in.readInt(); // number of grades

int[ ] f= new int [101]; // f[i] will contain the no.

// of times grade f appears

// Initialize frequencies f[k] to 0.

int k= 0;

// Inv: Each element of f[0..k-1] is 0

while (k != f.length)

{f[k]= 0; k= k+1;}
