Test instructionsA non-direction graph with 1 edge weights is given, and the maximum loop in the graph is obtained.Analysis:The Tarjan algorithm is generally used to strongly connect components, which sequentially accesses each of the strong connected components of the graph, which requires the maximum ring, and the ring is part of the strong connected component, so you can access other points at each point when the time stamp is modified to achieve the purpose of continuous timestamp on each ri

the next cycle. 5, pass statement, as the name implies, what is not dry, is a purely coding logic things. Some places require code in syntax, but Python does not have a corresponding empty curly brace or semicolon (;). To mean "don't do anything" in C, and if you don't write any statements where you need a block of child statements, the interpreter will prompt you for a syntax error. As a result, Python provides a pass statement 6, Else statement, in addition to the IF condition statement, in
