链接:Codeforces 1006C - Three Parts of the Array 大意:给你一串长度为n的数列,要你将其分成从左到右3个连续的子数列,每个数字属于且仅属于其中一个子数列,且sum1=sum3,求最大的sum。(1<=n<=2e5,1<=ai<=1e9) 思路:水题,处理出数列的前缀和,则可以从左右两侧出发,向中间搜索,左侧数列和小则递增...

You are given an array d1,d2,…,dnd1,d2,…,dn consisting of nn integer numbers. Your task is to split this array into three parts (some of which may be empty) in such a way that each element of the array belongs to exactly one of the three parts, and each of the parts forms...

We have an array of n length and we want to divide it into three parts such that after dividing the array sum of individual arrays should be as close to the power of 2 greater than or equal to the sum as possible. More formally, let say sum1, sum2, sum3 are the sums of subarray...
Your task is to split this array into three parts (some of which may be empty) in such a way that each element of the array belongs to exactly one of the three parts, and each of the parts forms a consecutive contiguous subsegment (possibly, empty) of the original array. ...
