1)和maxSum( 2)两种情况; 当sum > 0 时, 有 maxSum(2) + (k-2)*sum. Java代码classSolution{publicintkConcatenationMaxSum(int[] arr,intk){if( arr.length ==0|| arr ==null)return0;if(k <3)return(int) (maxSum(arr, k)%(1e9+7));longsum =0;for(intnum:arr) sum += num;lon...
You are given an array of positive integers nums and want to erase a subarray containing unique elements. The score you get by erasing the subarray is equal to the sum of its elements. Return the maximum score you can get by erasing exactly one subarray. An array b is called to be a ...
题目不算太难的。 classSolution{publiclongmaxMatrixSum(int[][]matrix){long sum=0;int counter=0;int min=Integer.MAX_VALUE;int n=matrix.length;for(int i=0;i<n;i++){for(int j=0;j<matrix[0].length;j++){if(matrix[i][j]<0)counter++;matrix[i][j]=Math.abs(matrix[i][j]);if(...
[LeetCode] 1695. Maximum Erasure Value You are given an array of positive integersnumsand want to erase a subarray containing unique elements. The score you get by erasing the subarray is equal to the sum of its elements. Returnthe maximum score you can get by erasing exactly one subarray....
Return the maximum sub-array sum in the modified array. Note that the length of the sub-array can be 0 and its sum in that case is 0. As the answer can be very large, return the answer modulo 10^9 + 7. Example 1: Input: arr = [1,2], k = 3 ...
给你一个整数finalSum。请你将它拆分成若干个互不相同的正偶数之和,且拆分出来的正偶数数目最多。 比方说,给你finalSum = 12,那么这些拆分是符合要求的(互不相同的正偶数且和为finalSum):(2 + 10),(2 + 4 + 6)和(4 + 8)。它们中,(2 + 4 + 6)包含最多数目的整数。注意finalSum不能拆分成(2...
1691. 堆叠长方体的最大高度本着做完3题溜之大吉的心态试了一试竟然碰对了，意外收获~
Explanation: Because we can choose [1, -2, 0, 3] and drop -2, thus the subarray [1, 0, 3] becomes the maximum value. Example 2: Input: arr = [1,-2,-2,3] Output: 3 Explanation: We just choose [3] and it's the maximum sum. ...
LeetCode 325. Maximum Size Subarray Sum Equals k 若谷 追求卓越,成功就会在不经意间追上你 题目: Given an array nums and a target value k, find the maximum length of a subarray that sums to k. If there isn't one, return 0 instead. Note:The sum of the entire nums array is guaranteed...
