Today, I tried to compile goahead. We can see that the goahead document contains information about how to use matrix to support SSL. The required matrix version in this document is 3.1.2, but the official website did not find this version to download. So I downloaded the latest 3.4.2 and modified the makefile. the following error occurs when the compilation result is used! Root @ jack-desktop :~ /Sof

Write an efficient algorithm, searches for a value in a m x n Matrix. This matrix has the following properties: Integers in each row is sorted from the left to the right. The first integer of each row was greater than the last integer of the previous row. For example,Consider the following matrix:[ [1, 3, 5, 7], [Ten, One,], [23, 30, 34,
