--description--
由参数{(x0,y0,z0),(dx,dy,dz)}指定的轴对齐长方体由所有点(X,Y,Z)组成,使得x0≤X≤x0+ dx,y0≤ Y≤y0+ dy且z0≤Z≤z0+ dz。长方体的体积是乘积,dx×dy×dz。长方体集合的总体积是它们的并集体积,如果任何长方体重叠,它将小于各个体积的总和。
设C1,...,C50000是50000轴对齐长方体的集合,使得Cn具有参数
x0 = S6n-5模10000y0 = S6n-4模10000z0 = S6n-3模10000dx = 1 +(S6n-2模399)dy = 1 +(S6n-1模399)dz = 1 +(S6n模399)
其中S1,...,S300000来自“Lagged Fibonacci Generator”:
对于1≤k≤55,Sk = [100003 - 200003k + 300007k3](模1000000)对于56≤k,Sk = [Sk-24 + Sk-55](模1000000)
因此,C1具有参数{(7,53,183),(94,369,56)},C2具有参数{(2383,3563,5079),(42,212,344)},等等。
前100个长方体C1,...,C100的总体积为723581599。
所有50000个长方体的总体积是多少,C1,...,C50000?
