R语言是由R统计计算基金会支持的统计计算和图形的编程语言和自由软件环境。统计学家和数据挖掘者广泛使用R语言来开发统计软件和数据分析。数据挖掘调查和学术文献数据库研究显示，受欢迎程度显著提高。截至2020年6月，R在TIOBE指数中排名第九，这是一个衡量编程语言受欢迎程度的指标。R是一个GNU软件包，一个正式的R软件环境，主要是用C、Fortran和R本身编写的(因此，它是部分自主的)，并且可以在GNU通用公共许可证下免费获得。为各种操作系统提供预编译的可执行文件。虽然R有一个命令行界面，但也有几个第三方图形用户界面，如集成开发环境RStudio和笔记本界面Jupyter。

随着越来越多人对作业代写需求的提升，相关的作业代写机构越来越多。有些人提出疑问：网上的作业代写服务可信吗？靠谱吗？这个问题没有确切答案，选择了靠谱的代写机构，自然靠谱又安全。特别是在美国、加拿大、澳洲上学的留学生朋友，现在很多都选择了ECON经济学专业，那么在遇到Assignment或者Essay这类作业的时候，是需要经济代写服务的，如果选择了不太靠谱的代写机构，可能会影响due以及最终的GPA。

Problem 1.(17 points) In performing search of a graph we get a tree where atree edge(u, v) indicates thatvhas not been visited when we examine this edge while we visitu. We have the following 3 types of non-tree edges: (a)back edge(u, v) is a non-tree edge such thatvis an ancestor ofuin the tree discovered when we visitu, (b)forward edge(u, v) is a non-tree edge such thatvis a descendant ofu discovered when we visitu, (c)cross edge(u, v) is a non-tree edge such that vis neither a descendant of nor an ancestor ofudiscovered when we visitu. (a) Show the DFS and BFS tree of the following directed graph starting from vertexv 1 showing clearly the tree edges and for non-tree edges mark them as one of the above 3 types (back,forward,cross).Assume that vertices in the ad- jaceny list of a vertex are stored in increasing order of its indices.(11 points)
