This problem is similar to a standard problem but it has a different format and constraints. In the standard problem you are given an array of integers, and you have to find one or more consecutive elements in
I tried to code solution for the Segment With Maximum Sum problem from the Segment Trees Section in ITMO pilot course.Link To the Question classSgtree{private:vl seg,pref,suff,sum;int_n;voidleaf_update(ll node,ll val){pref[node]=val;suff[node]=val;seg[node]=val;sum[node]=val;}void...
C. Little Girl and Maximum Sum题意给q个[l,r]将所有这些区间里面的数相加和最大。 可以进行的操作是任意排列数组题解对出现的每个区间内的位置加上1,代表权值 操作完之后求一遍前缀和,得到每个位置的权值 然后贪心的考虑,权值越大,应该分配给该位置的数越大越好这样对答案的贡献最大。
Now to combine two arrays, the maximum subarray sum of the combined array would bemax(p(1)2,p(2)2,p(1)2+p(1)3+p(2)1+p(2)2)max(p2(1),p2(2),p2(1)+p3(1)+p1(2)+p2(2)). The remaining left and right side parts can be maintained easily. ...
【Codeforces1519D】Maximum Sum of Product(数学) 题目大意: 给出两个长度为n(1≤n≤5000)的数列,对一个数列的子段进行至多一次翻转操作,求两数组同下标数之积的总和的最大值。 由数据范围可知本题时间复杂度需控制在Θ(n2)以内。我们考虑先枚举翻转区间的中心,再从中心向两边扩展区间,同时用得到的结果来...

【Codeforces 276C】Little Girl and Maximum Sum,【链接】"我是链接,点我呀:)"【题意】在这里输入题意【题解】最后的和。其实可以看成是∑biai的形式。这里的bi这个系数表示的是有多少个区间覆盖了ai这个元素。既然这样的话。那么我们可以用个技巧li++,ri的技巧算出来每个
Find the maximum possible value ofgcd(a1,a2,…,an)+gcd(b1,b2,…,bn)\gcd(a_1, a_2, \ldots, a_n) + \gcd(b_1, b_2, \ldots, b_n)gcd(a1,a2,…,an)+gcd(b1,b2,…,bn)that you can get by paying in total at mostdddcoins for swapping some ...
