Please hand write the solution, with clear drawings and explanation. Will leave good review 

Let the degree sequence of a graph G be the sequence of length |V (G)|
that contains the degrees of the vertices of G in non-increasing order.

sequence, or explain why such a graph does not exist:
a. (4, 2, 2, 1, 1)
b. (4, 3, 3, 2, 1)
c. (2, 2, 2, 1, 1)
d.
(4, 4, 4, 2, 2)
e. (3, 3, 3, 2, 1)
