1. Suppose we start with a max heap (a 1-indexed list A) containing the following elements not [12 pts]
in the order given:
{10, 20, 30, 40, 50, 60, 70}
We swap A[1] and A[7], chop off A[7], then run maxheapify on A[1].
Suppose we know what A looks like after this process and we know where 20 was before this
process. What the rest of it look like before?

Determine the required volume of a completely mixed activated sludge aeration
tank for a conventional activated sludge system treating a design flow rate of
34,560 m³/d, where the effluent standards are 30.0 mg/L for BOD5 and 30.0 mg/L
for total suspended solids (TSS). Assume that the BOD5 of the effluent TSS is 70%
of the TSS concentration. Assume the BOD5 concentration leaving the primary
clarifier is 128 mg/L that the MLVSS concentration (Xa) is 2,500 mg/L. Assume the
following values for the growth constants:
•
K = 100 mg/L BOD5
• μm = 2.5 d−1
•
kd = 0.050 d 1
Y = 0.50 mg VSS/mg BOD5 removed
Express your answer in m³ and round to the nearest integer.
4. Suppose we have a perfect binary tree with height h 0 representing a heap, meaning it
=
has n 2+1 1 keys indexed from 1 to 2+1 1. When we run convertomaxheap we run
maxheapify in reverse order on every key with children.
Let's examine the worst-case - In the worst-case every single key gets swapped all the way to
the leaf level.
(a) For each level in the tree there are a certain number of nodes and each of those nodes [10 pts]
requires a certain number of swaps. Fill in the appropriate values/expressions in the
table:
Level
Number of Keys
Number of Swaps per Key

(b) Write down a sum for the total number of swaps required. This should involve h, not n.
