for just max sum subarray it is Kadane's algorithm in O(n) time, however, I couldn't think of a way to solve for atleast 2 numbers faster than O(n^2). Any idea or a solution?
// you cannot add this in this subarray, make new one // say you add this num in new subarray, then sum = num sum = num; pieces++; } else { sum += num; } }if (pieces > m) { start = mid + 1; } // else if (pieces <= m) { end = mid }; ...
For each test case, you should output a line contains three integers, the Max Sum in the sequence, the start position of the sub-sequence, the end position of the sub-sequence. If there are more than one result, output the minimum start position, if still more than one , output the m...
First thing to note is that sum of subarray(i,j]is just the sum of the firstjelements less the sum of the firsti elements. Store these cumulative sums in the array cum. Then the problem reduces to findingi,jsuch thati<j andcum[j]−cum[i] is as close tok but lower than it. ...
以及这道题目:max subarray sum no more than k 本题基本上是以上两种思路的组合了,具体的实现很简单。 题目描述 Given a non-empty 2D matrix matrix and an integer k, find the max sum of a rectangle in the matrix such that its sum is no larger than k. ...
We define the cost FF of a subarray A[i,j]A[i,j] to be min(Ai,Ai+1,...,Aj)∗max(Ai,Ai+1,...,Aj)min(Ai,Ai+1,...,Aj)∗max(Ai,Ai+1,...,Aj). The cost GG of a partition is the sum of FF for all its subarrays. Print the sum of GG for all 2N−12N−...

Also, subset of consecutive elements is probably better defined as subarray. avidcoder:2017-08-15 09:11:39 Weak test cases! Since it is a tutorial problem. It's okay. Last edit: 2017-08-15 09:33:11 Francky:2014-12-28 16:33:34 ...
