题意:有一些男生女生,男生女生数量差不超过100 ,男生女生两两配对.要求求出一种配对方法,使每一对的高度差的和最小. 思路:(我是真的笨笨笨!!)设人少的一组人数为n,b[],人多的一组人数为m,g[](b[],g[]先排好序),用dp[i][j]表示n中的前i个人与m中的前j个人配对所得到的最小值. 对于每个i,j的范围是(i~i+m-n) 这样j的范围是i~m-n+i,对于dp数组而言,第二维数组要开到m,由于数组过大,而我们又知道,m-n<=100,所以用j表示j-i,j的范围就变成了(…

[分析] “虽然不是求什么最大的最小值(或者反过来)什么的……但还是可以用二分的,因为之前就做过一道小数型二分题(下面等会讲) 考虑二分面积,下界L=0,上界R=∑ni=1nπ∗ri2.对于一个中值x和一张半径r的饼来说,这张饼能够分出的最多分数显然是:⌊π∗r2x⌋,所以我们只需要求出∑ni=1⌊π∗ri2x⌋,判断其与f+1的关系即可 特别要注意的一点:π的大小!,因为r≤104r≤104,所以r2≤108r2≤108,又因为题目要求精确到三位小数,所以ππ就要精确到10-11,即π=3.1…
