题目链接:fzu 1911 Construct a Matrix 题目大意:给出n和m,f[i]为斐波那契数列,s[i]为斐波那契数列前i项的和.r = s[n] % m.构造一个r * r的矩阵,只能使用-1.0.1.使得矩阵的每行每列的和都不相同,输出方案,不行的话输出No. 解题思路:求r的话用矩阵快速幂求,每次模掉m, { {1, 1, 0}, {1, 0, 0}, {1, 1, 1} } * { f[i], f[i -1], s[i] } = { f[i + 1], f[i], s[i…

题目链接:Construct a Matrix 题意:构造一个矩阵,要求矩阵的每行每列的和都不相同.矩阵的边长是前n项斐波那契的和. 思路:由sn = 2*(fn-1)+(fn-2)-1,只要知道第n-1和第n-2项即可,n的范围是10^9,可由矩阵快速幂求出第n项.然后,构造矩阵,上三角为1,下三角全为-1,对角线1和0交替.[真是个天才...!!!]矩阵快速幂求第n项时,构造的矩阵是a[0][0] = f2, a[1][0] = f1, a[0][1] = 1, a[1][1] = 0...…
