C++解答

#include <stdio.h>
int main() {
	int a, b, c, t;
	scanf("%d %d %d", &a, &b, &c);
	/* 首先比较a和b的关系，通过交换位置使a <= b */
	if (a > b) {
		t = a;
		a = b;
		b = t;
	}
	/* 比较a和c的关系，通过交换位置使a <= c，从而a是最小值 */
	if (a > c) {
		t = a;
		a = c;
		c = t;
	}
	/* 比较b和c的关系，通过交换位置使b <= c，最终使a <= b <= c*/
	if (b > c) {
		t = b;
		b = c;
		c = t;
	}
	printf("%d %d %d\n", a, b, c);
	return 0;
}

Java解答

import java.util.Scanner;

public class Main{

	public static void main(String[] args) {
	Scanner s=new Scanner(System.in);
	int a=s.nextInt();
	int b=s.nextInt();
	int c=s.nextInt();
	int t;
    if (a > b) {
        t = a;
        a = b;
        b = t;
}
if (a > c) {
        t = a;
        a = c;
        c = t;
}
if (b > c) {
        t = b;
        b = c;
        c = t;
}		
System.out.print(a+" ");
System.out.print(b+" ");
System.out.print(c);
	}
