This time your job is to fill a sequence of N positive integers into a spiral matrix in non-increasing order. A spiral matrix is filled in from the first element at the upper-left corner, then move in a clockwise spiral. The matrix has m rows and n c…

题意:给定N,以及N个数.找出满足m*n=N且m>=n且m-n最小的m.n值,建立大小为m*n矩阵,将N个数从大到下顺时针填入矩阵中. #include <iostream> #include <cstdio> #include <algorithm> #include <string.h> #include <cmath> #define LEFT 1 #define RIGHT 2 #define UP 3 #define DOWN 4…

题意:输入一个正整数N(实则<=1e5),接着输入一行N个正整数(<=1e4).降序输出螺旋矩阵. trick: 测试点1,3运行超时原因:直接用sqrt(N)来表示矩阵的宽会在N是素数时出错,直接扫一遍找一个最大因子即可,简单粗暴. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ]; ][]; int main(){ ios::sync_wi…
