    算法思想 :

    对分母进行分解:

    n可以分解成     1/n  =  1/(n+1)   +  1/(n+1)*n  

    例如   从2 3 6 开始

    不能有相同的 所以只能从 2分解成 3 6 前面已经含有了,然后只能从3开始改

    下一项变成 2 4 6 12

    下一项不能分解 2因为会多出来6 所以应当选择 2 5 6 12 20

    题意
    分别用3到18个数 的倒数相加 等于1   
    并且每个数要求 小于等于 个数+1的平方
    比如 用3个数 
    那么要找3个数满足 这三个数小于等于(3+1)*(3+1) 且倒数之和为1
     
    思路:
    一个倒数可以分解问2个数的倒数之和 
    1/n= 1/(a*b)=1/a*(a+b) + 1/b*(a+b)
     
    故 在已知 上层的情况下 可以直接将上一层的数分解为2个数  以此类推即可
     
    手算  我没有写程序 
    #include<stdio.h>
    int main()
    {
    	
                	printf("2 3 6\n");
                	printf("2 4 6 12\n");
    				printf("2 5 6 12 20\n");
    				printf("2 5 7 12 20 42\n");
    				printf("3 5 6 7 12 20 42\n");
    				printf("3 5 6 8 12 20 42 56\n");
    				printf("3 5 6 8 16 20 42 48 56\n");
    				printf("3 5 6 12 16 20 24 42 48 56\n");
