[Copy question]:In a sort matrix, find the first k integer from small to large.The sort matrix is defined as: Each row is incremented, and each column is incremented.[Thinking questions]:Do not know how to add, because it is not one-dimensional
1. The problem arises
This problem is caused by the "3D Game Programming Master Skills" in the book some of the problems are not clear, some things are not right.
The first aspect of this noun is because our PC screen is not square and the screen
In the previous chapters, the bubble sort, insert sort, select sort, and merge sort are described separately. In the introduction of hashing technology, the bucket sorting, counting sorting and odd sorting were also introduced. When discussing the
Count sort1, the algorithm thought:The counting sort is the deformation of the direct addressing method. By opening up a certain amount of space, the number of occurrences of the same data is counted and then written back to the original sequence.2.
Matrix transpose: a matrix refers to a two-dimensional data table in a vertical and horizontal arrangement.Prime number calculation: Prime number formula, also known as the prime number formula, indicates a formula that can only generate prime
