Give you an array num containing n integers. Judge whether there are three elements a, b and c in num, so that a + b + c = 0? Please find all triples with sum 0 and no repetition. Note: the answer cannot contain duplicate triples. Example 1: Input: num = [- 1,0,1,2, - 1, - 4] Output: [- 1, - 1,2], [- 1,0,1]] Example 2: Input: num = [] Output ...

preface This paper is a summary of computer graphics experiments. The experiments are written in glad and glfw. There are still many imperfections in the code. For example, the operations of drawing lines and polygons can be reasonably encapsulated to form a perfect graphics header file and even namespace, which is very helpful to the foll ...
