Subject: A typo in Question 2 (homework number 1)

Dear Students,

Mira pointed out to me a typo in that question, which causes confusion:
It should be: 
if $(u,v) \in E$ then $M_G[u][v] = +1$ and otherwise $M_G[u][v] = -1$.
And the answer to a query (u,v) is M_G[u][v].

Let me know in case anything else is unclear.

Dana.

Subject: Homework number 2

Dear Students,

There are some corrections to typos in homework number 2 (thanks Mira).
I think it will be easiest if you simply take down the new version from the
website (hopefully not many of you were too prompt about solving the
homework...)

Dana.

p.s. Please acknowledge receipt of this email so that I'll know who got it.
