Memory leaks | 17 Aug 2018 21:26 | 5 | first for bound=1e5,using matirx power to compute x0,x1 x[bound],x[bound+1] ,x[2*bound],x[2*bound+1]..... upper bound is 2*p using map to record (x[i*bound],x[i*bound+1]) I use this formula and discrete log algo to find candidate of xn+1 then continue to compute xn-1 xn-2 .... until we find (xi,xi+1) in the map then it is valid otherwise it is invalid complex : sqrt(p*log(p)) Edited by author 02.12.2017 15:17 Could you do me a favor to explain the meaning of this problem? My teammates and me are working on this but we can hardly get the point. Thx for helping anyway. p.s. Chinese would be better XD 给定 斐波那契 的某一项 %p的值x,求它的下一项 %p的所有可能值 |
