Use Python only and take input from
files called "input.txt", and output at
"output.txt".

output.txt file.
a. Study the algorithm below and implement
quickSort method . Additionally you will also
need to implement the "partition" method.
After sorting print both the unsorted array and
sorted array and also the time it takes to
complete sorting.
Algorithm
QUICKSORT(A, p, r) ► A[p.r]
1 if p<r
then q – PARTITION(A, p, r)
QUICKSORT(A, p, q – 1)
QUICKSORT(A, q + 1, r)

4
Algorithm
PARTITION(A, p, q) D A[p..q]
x- A[p]
1
D pivot = A[p]
for j – p+ 1 to q
do if A[j] < X
3

5
then i – i+1
exchange A[i] → A[j]
A[i]
exchange A[p]
return i
b. Implement an algorithm "findK" that uses
the "partition" algorithm to find the kth
(smallest) element from an array without
sorting. E.g. for the array in our example, the
5th element will be "9"
