I have huge list of edges with weights.
a1 b1 w1
a2 b2 w2
a3 b3 w3
a1 b1 w4
a3 b1 w5
I have to convert it into 2 dim matrix
     b1                b2          b3
a1  max(w1,w4)   0           0
a2            0        w2         0
a3        w5          0           w3

if edges repeated take the maximum weights. How do this efficiently without
using for loop? Any idea.

thanks
Avi
