定义计算矩阵转置的函数 1)使用循环进行转置 matrix = [[1, 2, 3, 4],[5, 6, 7, 8],[9, 10, 11, 12]]
给定一个二维矩阵,计算其子矩形范围内元素的总和,该子矩阵的左上角为 (row1, col1) ,右下角为 (row2, col2) 。
matrix = [[1,2,3,4],[5,6,7,8],[9,10,11,12]]

题目Given an image represented by an NxN matrix, where each pixel in the image is 4 bytes, write a me
A boolean matrix has the parity property when each row and each column has an even sum, i.e. contains an even number of bits which are set. Here’s a 4 x 4 matri...
