There are a column of marks on hardcopies of assignment 2. 
For example: 


a+b
c+d
e
f
g
h
i
j


They are interpreted as follows: 

a (out of 15) Correctness of conversion of the input to the specific
              data structure (theoretically).
b (out of 5)  Style and comments regarding the previous part.
c (out of 15) Correctness of Prim algorithm (theoretically). 
d (out of 10) Style and comments regarding the previous part.
e (out of 5)  Correctness of the matrix generator (theoretically).
f (out of 4)  Running time report.
g (out of 6)  Presenting 3 real world application of MST. 
h (out of 20) Execution of the prim algorithm.
i (out of 5)  Execution of the matrix generator
j (out of 15) Execution of the program (7 test cases)
