In a given array nums of positive integers, find three non-overlapping subarrays with maximum sum. Each subarray will be of size k, and we want to maximize the sum of all 3*k entries. Return the result as a list of indices representing the starting position of each interval (0-indexed)...
int three_square(ll x){ while (!(x&3)) x>>=2; return (x+1)%8; } It returns 0, if x is not a sum of three squares. → Reply CherryTree 13 years ago, # ^ | +5 How come? → Reply Tranvick 13 years ago, # ^ | 0 This is a very difficult method of pen ...
Then each of n lines contains the description of one of the three operations: add x — add the element x to the set; del x — delete the element x from the set; sum— find the sum of medians of the set. For any add x operation it is true that the element x is not included...
CodeForces -1467D Sum of Paths 动态规划 题意 定义一条好的路径为从任意点出发后恰好进行了$k$次移动产生的路径,这条路径的权值和为走过的点的权值和。 进行$q$次修改,每次将$a_k$改为$x$,修改后询问此时所有好的路径的权值和。 分析 每次询问,都不会使原来的好路
