在保持代码一定可读性的同时，还极限压行进了十行，什么实力，不用说了

点个赞吧QAQ

#include <bits/stdc++.h> using namespace std; int main() { int N; cin>>N; vector<vector<int>>magicSquare(N,vector<int>(N,0)); int row=0; int col=N/2; for(int num=1;num<=N*N;num++){ magicSquare[row][col]=num; int nextRow=(row-1+N)%N; int nextCol=(col+1)%N; if(magicSquare[nextRow][nextCol]!=0)row=(row+1)%N; else{ row=nextRow; col=nextCol; } } for (int i=0;i<N;i++) { for(int j=0;j<N;j++)cout<<magicSquare[i][j]<<" "; cout<<endl; } return 0; }

#include <bits/stdc++.h> using namespace std; const int N = 1001; int n,a[N][N],m; int main() { cin>>n; int x=1,y=(n/2)+1; for(int i=1;i<=n*n;i) { a[x][y]=i; if(x==1 and y!=n) { x=n; y; } else if(yn and x!=1) { y=1; x--; } else if(x1 and y==n) { x++; } else if(x!=1 and y!=n and a[x-1][y+1]==0) { x--; y++; } else x++; } for(int i=1;i<=n;i){ for(int j=1;j<=n;j){ cout<<a[i][j]<<" "; } cout<<endl; } }

用I,J定位，再做判断就行。 #include<iostream> using namespace std; int n,a[45][45],I,J; int main(){ cin>>n; I=0; J=n/2; for(int i=1;i<=n*n;i++){ a[I][J]=i; if(I-1<0&&J+1<n){ I=n-1; J++; } else if(I-1>=0&&J+1>=n){ I--; J=0; } else if(I-1<0&&J+1==n||a[I-1][J+1]){ I++; } else{ I--; J++; } } for(int i=0;i<n;i++){ for(int j=0;j<n;j++){ cout<<a[i][j]<<' '; } cout<<endl; } return 0; }

#include<bits/stdc++.h> int n, a[40][40], lasti, lastj; int main() { 面附原if_else加三目版 for (int i = 1; i <= n; ++i) { for (int j = 1; j <= n; ++j)printf("%d ", a[i][j]); printf("\n"); } return 0; }
