题目地址:http://acm.hdu.edu.cn/showproblem.php?pid=4193 题意:给出一个n数列,要求把前i(1<=i<=n)个数移到剩余数列的后面形成新的数列,如果新数列满足前i(1<=i<=n)个数均大于等于0,算一种情况,问总共有多少种情况. 简单思路:单调队列+前缀和,枚举每一个可能的以i为首的数列,用单调队列找出区间[i,i+n-1]的最小前缀和,如果最小前缀和sum[k]-sum[i-1]>=0,就可能算一种,并在枚举的时候更新单调队列…

HDU 4193 题意:给n个数字组成的序列(n <= 10^6).求该序列的循环同构序列中,有多少个序列的随意前i项和均大于或等于0. 思路: 这题看到数据规模认为仅仅能用最多O(nlogn)的算法.然后想到了之前刚做过的有关最小表示法的题.但还没证明出一个做这题有效的算法出来. 后来看过题解.发现用的最多的方法是单调队列,然而我对这个知识点知之甚少orz /*科普君:from单调队列 单调队列是指:队列中元素之间的关系具有单调性.并且,队首和队尾都能够进行出队操作.仅仅有队尾能够进行入队操作…
