问题描述 勤奋的Farmer John想要建造一个由四面围成的栅栏来关住那些奶牛。他现在有一块长度为N(4 <= N <=100000)的长木板,他需要把这块长木板切成边长均为正整数的四块,使得他能建造一个栅栏。请问他有多少种不同的切割方式能使切割出来的木板围成一个四面的栅栏。 注意: 1. 四边形即可,不一定是矩形。
证明:设四边为a,b,c,d。因为有a < b+c+d,所以2*a < a+b+c+d = 周长,所以a < 周长/2。 *f[i][j]:i条边,总长为j的方案数 求=f[4][n]; for(int i=1;i<=4;i++) for(int j=1;j<=n;j++) int k=min(j,Len); f[i][j]=f[i-1][j-k](1<=k<min(j,n/2))=sum...
