题解:
a1*x13+a2*x23+a3*x33+a4*x43+a5*x53 = 0
<==> a1*x13+a2*x23+a3*x33 = -1*(a4*x43+a5*x53)
可以想办法利用三重循环枚举x1,x2,x3,算出a1*x1^3+a2*x2^3+a3*x^3得到的所有的100*100*100个值,先储存起来,假设存在a[ ]数组里。然后利用两重循环枚举x4,x5,逐个算出-1*(a4*x4^3+a5*x5^3)的所有值,如果这个值也存在于a[ ]中,就代表找到一组可行解,答案+1。
现在的问题就变成了如何快速的查找a[ ]中的值,如果从头到尾扫一遍,那时间复杂度和直接五重循环枚举没有什么区别。
这个问题可以用哈希表优化,先不解释哈希表是什么。先考虑如下问题:
如果要存储和查找线性表(1,75,324,43,1353,90,46),有两种基本的思路:一种是定义一个数组A[10],把它们依次存入,但是这会给查找操作带来O(n)的时间复杂度,当数字非常多时,效率也许不可接受;第二种方法是定义数组A[2000],把这几个数字作为下标,即A[1]=1,A[75]=1,A[324]=1,A[43]=1,A[1353]=1,A[90]=1,A[46]=1,这样查找有没有x时只需判断A[x]是否等于1就可以了时间复杂度O(1),但是这种方法的问题也很大,就是空间浪费多,空间复杂度高。
现在考虑优化第二种方法,假设我们设计函数h(x) = x mod 1235789 ,把原来的A[x]=1的操作变成A[ h(x) ] = 1 ,这样一来把数组大小设置为1235789就可以了。这样做也存在一定的问题: a != b 但 h(a) = h(b) = val 的情况是肯定存在的。问题也好解决,假设有m个数的h( )值都等于val,不妨把这m个值都用邻接表存起来(大致相当于A数组变成二维数组,只是第二维长度不定,m个数都存在A[ val ][ ]里 ),当要找q在不在A里时,就在A[ h(q) ][ ]里找,这个查找量比在所有数字中找要小的太多太多了,因为第二维会很短,毕竟h(a)=h(b)的情况并不多。
看懂了上述问题及分析也就知道了这个题怎么做,a1*x1^3+a2*x2^3+a3*x^3得到的所有的100*100*100个值就相当于上面1,75,324那7个值,逐个算出的 -1*(a4*x4^3+a5*x5^3)的所有值就相当于要查找的q,把答案统计出来即可。
注意:负数取模存在问题,而a1*x1^3+a2*x2^3+a3*x^3 与 (a4*x4^3+a5*x5^3)要想成为一组解,肯定互为相反数,不妨用unsigned long long 或 unsigned int类型再取模。
