Can anyone please solve the question number 2 of this question?

1. a 12 Vs us 13 V4 S: x:=0 S2: x:=x + 1 Sz: y := 2 S4:2:= y Ss: x:=x + 2 S6: y = x + Z $7:2:= 4 Fig. 1 Fig. 2 Fig. 3 Determine whether the directed graph in Fig. 1 has an Euler circuit. Construct an Euler circuit if one exists. If no Euler circuit exists, determine whether the directed graph has an Euler path. Construct an Euler path if one exists. Construct a precedence graph for the program in Fig. 2. a) 3 b) 2. a) 3 Find the incidence matrix of the graph in Fig. 1 with respect to the vertices listed in alphabetic order. b) Determine whether the pair of graphs in Fig. 3 and Figure 4 are isomorphic. 3
