line as max but total as sum of MAX 02-20-2024 01:49 AM Hi guys, I've values on 12 columns, 1 per month. I thought to unpivot all of them, so I could use a column for the date and another for values. Problem is, when I create a matrix or a table, it SUM all the...
Max Sub-matrix Max Sub-matrix 教练找的题目,目前样列过了 题意:找子矩阵的最大周长 思路:先离散每列,再枚举列(n*n),在当前枚举的两列之间求每行的和(n*n*n),但是开两个数组,一个包含两列上的元素 一个不包含,这样可以处理出前i行当前这两列上的元素和。 当前两列中每行元素和知道 两列上前i...
