https://leetcode-cn.com/problems/intersection-of-two-arrays/solution/acm-xuan-shou-tu-jie-leetcode-liang-ge-s-qzbi/ 就一句话:求两个数组的交集,直白点儿就是【nums2 的元素是否在 nums1 中】。 需要注意一下“提示”里讲的:输出结果中的每个元素一定是唯一的,翻译一下就是去重输出。
题目地址:https://leetcode.com/problems/reshape-the-matrix/description/题目描述In MATLAB, there is a very useful function called ‘reshape’, which can reshape a matrix into a new one with different size but keep its original data.You’re given a matrix represented by a two-dimensional array...
I. 行列式(Determinants)和迹(Trace) 1. 行列式(Determinants) 为避免和绝对值符号混淆,本文一般使用$det(A)$来表示矩阵$A$的行列式。另外这里的$A∈R^{n×n}$默认是方阵,因为只有方阵才能计算行列式。 行列式如何计算的就不在这里赘述了,下
