Leetcode12: Search a 2D Matrix
Write an efficient algorithm that searches for a value in an m x n matrix. This matrix has the following properties:
Integers in each row are sorted from left to right.
The first integer of each row is greater than the last integer of the previous row.For example,Consider the following matrix:[ [1, 3, 5, 7], [10, 11, 16, 20], [23, 30, 34, 50]]Given target =3, Returntrue.This is an young matrix, that is, each r

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.

very, very simple, and the only purpose now is to instantiate the Gamemanager. "Why does a similar soundmanager not have to be instantiated in code?" "Because there's already a soundmanager in the hierarchy view that we dragged in, kid! ”In fact, there are other things that can be done in addition to instantiating Gamemanager, but in this case there is not much work to do, so this is the only thing to do here first.In addition, if a script wants to run, the one thing necessary is to cling to a

unified method for computing. The smart computer graphics scientists have designed such a coordinate system called homogeneous coordinates, the purpose is to use a matrix to calculate the transformation of a graph more conveniently. So what is homogeneous coordinates? In fact, it is in the original 2D dimension, plus a new dimension. The value of the extra dimension is always 1. For example, the dot matrix is changed:
