使用这个代码生成

#include <cmath>
#include <cstdio>
using namespace std;

const double DEGPAI = atan( 1.0 ) / 45.0;

int main() {
    freopen( "p1429_hack.txt", "w", stdout );


    printf( "%d\n", 360 * 10 + 2 );
    printf( "%lf %lf\n%lf %lf\n", 0, 0, cos( DEGPAI * 0.5 ), sin( DEGPAI * 0.5 ) );
    for( int i = 0; i < 360; ++i ) {
        double qx = cos( DEGPAI * i ), qy = sin( DEGPAI * i );
        for( int j = 60; j < 80; j += 2 ) printf( "%lf %lf\n", qx * j, qy * j );
    }


    return 0;
}
