输入3个数a,b,c，按大小顺序输出。

题目：输入3个数a,b,c，按大小顺序输出。

思路: 根据最简单的, 经典的C语言算法, 两两相互交换得到他们的顺序

public class 第三十四题abc三个数大小排序 {
    public static void main(String[] args) {
        Integer a = new Integer(10);
        Integer b = new Integer(6);
        Integer c = new Integer(9);
        int[] result = sort(a,  b,  c);
        for(int m:result) {
            System.out.print(m+" ");
        }
        
    }
    public static int[] sort(Integer a, Integer b, Integer c) {
        int temp;
        if(a > b) {
            temp = a;
            a = b;
            b = temp;
        }
        if(a > c) {
            temp = a;
            a = c;
            c = temp;
        }
        if(b > c) {
            temp = b;
            b = c;
            c = temp;
        }
        return new int[] {a,b,c};
    }
}
