pair!!! 东西不多,应该比较好理解。 一句话概括: pair只含有两个元素,可以看作是只有两个元素的结构体。 在应用上,其可以: 1.代替二元结构体 2.作为map键值对进行插入(map没学先不讲) 一、定义和使用pair: 东西挺少,我就一起放出了。 //头文件 #include<utility> //1.初始化定义 pair<string,int> ...

[29] the authors study the background and perturbative evolution of some interacting models using dynamical system methods, and they find that interaction can describe the matter and dark energy epochs correctly. On the other hand, the authors of Ref. [30] introduce the cosmological pair r and...
