An Elegant Solution

// For i in 0..100, freq[i] is # of grades of i.

int[] freq = new int[101];

/* �Process� grades until (but not including) a stopping signal of -1. */

/* Initialize 101 counters to 0. */

grade = 0;

while ( grade<=100 ) {

freq[grade] = 0;

grade = grade + 1;

}

grade = in.readInt();

while (grade != -1 ) {

/* Increment counter for grade. */

freq[grade] = freq[grade] + 1;

grade = in.readInt();

}

/* Print histogram. */

System.out.println(�Grade Frequency�);

grade = 0;

while ( grade <= 100 ){

System.out.println(

grade + � � freq[grade]

);

grade = grade + 1;

}
