Q3) A tourist plans to visit seven places of attractions in a country, namely A, B, C, D, E, F, and G. These places are connected with inter city railway links. The route across these places is as shown in Figure 3. Figure 2 a) Trace the journey of the tourist if he wanted to visit every place of attractions (A, B, C, D, E, F, G) exactly once starting and ending at E. b) Determine whether the tourist's journey in 3(a) is an Euler circuit or Hamiltonian circuit. c) If the intercity railway link from A to B is close due to maintenance work, plan the tourist's journey from A so he/she can still visit all the place of attractions and ends at any of the places following the Euler trail rules
