题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4655 题意:给出n个石子,第i个石子可以染ai种颜色.对于每种颜色,比如颜色1221,我们称有3段.连续相同的为一段.合理安排石子的顺序使得所有染色方案的总段数之和最大? 思路:对于给出的一个数列,我是打表找到如何安排位置使得最后的答案最大,就是: i64 a[N],p[N],q[N],d[N];int n; int main(){    rush()    {        RD(n);     …

http://acm.hdu.edu.cn/showproblem.php?pid=5806 题意:给你一个n元素序列,求第k大的数大于等于m的子序列的个数. 题解:题目要求很奇怪,很多头绪但写不出,选择跳过的题,简称想法题. 首先考虑区间的更新方法:区间左端l不动,右端r滑动, 滑到有k个数>=m时,此区间符合条件,并且发现右端点再往右滑到底,此条件一直符合(因为若加入的数小于“第K大的数”,则毫无影响.若不然,加入该数会产生一个新的第k大数,保证>=“第K大的数”>=m) 所以一找…
