• C

#include <stdio.h> 
#include <stdlib.h> 
#define MAX 100 
#define MIN 0 

int main(void) { 
 int score[MAX+1] = {0}; 
 int juni[MAX+2] = {0}; 
 int count = 0, i; 

 do { 
 printf("輸入分數，-1結束："); 
 scanf("%d", &score[count++]); 
 } while(score[count-1] != -1);

 count--; 

 for(i = 0; i < count; i++) 
 juni[score[i]]++; 
 juni[MAX+1] = 1; 

 for(i = MAX; i >= MIN; i--) 
 juni[i] = juni[i] + juni[i+1]; 

 printf("得分\t排行\n"); 
 for(i = 0; i < count; i++) 
 printf("%d\t%d\n", score[i], juni[score[i]+1]); 

 return 0; 
} 

• Java

import java.io.*;

public class ScoreRank {
 public static void main(String[] args) 
 throws NumberFormatException, IOException {
 final int MAX = 100;
 final int MIN = 0;
 
 int[] score = new int[MAX+1]; 
 int[] juni = new int[MAX+2];
 
 BufferedReader reader = 
 new BufferedReader(
 new InputStreamReader(System.in));
 int count = 0; 

 do { 
 System.out.print("輸入分數，-1結束："); 
 score[count++] = 
 Integer.parseInt(reader.readLine()); 
 } while((score[count-1] != -1));

 count--; 

 for(int i = 0; i < count; i++) 
 juni[score[i]]++; 
 juni[MAX+1] = 1; 

 for(int i = MAX; i >= MIN; i--) 
 juni[i] = juni[i] + juni[i+1]; 

 System.out.println("得分\t排行"); 
 for(int i = 0; i < count; i++) {
 System.out.println(score[i] + "\t" + 
 juni[score[i]+1]); 
 }
 }
