for part a it says draw, not give an explination. Q$9.(6$ points$)$ You are given the following tree:

$($a$)$ Draw Euler tour traversal of this tree. $(2$ points$)$

$($b$)$ Provide a parenthesized arithmatic expression that can be produced by this binary Euler tour. Provide steps to write the expression. $(2$ points$)$

$($c$)$ Describe the time complexity of the Euler walk in BigO notation and justify your answer $(2$ points$)$
