Given an integern, generate a square matrix filled with elements from 1 ton2 in spiral order. For example, Givenn=3, You should return the following matrix: [ [ 1, 2, 3 ], [ 8, 9, 4 ], [ 7, 6, 5 ] ] 1publicclassSolution {2publicint[][] generateMatrix(intn) {3intstartx...
Given a matrix of m x n elements (m rows, n columns), return all elements of the matrix in spiral order. For example, Given the following matrix: [ [ 1, 2, 3 ], [ 4, 5, 6 ], [ 7, 8, 9 ] ] You should return [1,2,3,6,9,8,7,4,5]. Solution 1: 使用递归,一次扫描...

目录(?)[+] list array matrix 用python中的numpy包的时候不小心踩了array和matrix的大坑,又引申一下比较list array matrix之间的异同 1、list list可以明显和array、matrix区分,list通过[ ]申明,支持append extend等方法,没有shape方法。 使用如下: data=[] data.append([1,2]... ...
