Question
![Given two arrays a and b, where both arrays consisting of n positive integers. It is allowed
to swap any element from array a with any element from b. Your task is to find
the maximum possible sum you can obtain in the array a if you can do no more than (i.e.
at most) k moves (swaps).
Input
• The first line of the test case contains two integers n and k (1Sns30;0sksn) -
where n is the number of elements in a and b, while k is the maximum number of
moves you can do.
• The second line of the test case contains n integers a1,a2,... an
• The third line of the test case contains n integers b1,b2,..,bn
Output
Print the answer – the maximum possible sum you can obtain in the array a if you can
do no more than (i.e. at most) k swaps.

• In the first test case of the example, you don't need to swap anything.
• In the second test case of the example, you can swap a1=1 with
bi=10, a3=3 with b3=10 and a2=2 with b4=10,
so a=[10,10,10,4,5] and b=[1,9,3,2,9].
• In the third test case of the example, you cannot swap anything.
a) Design a brute-force algorithm to solve this problem using a (Pseudocode) and find its
complexity.
b) Can you design a more efficient solution? If yes, demonstrate it using Pseudocode
and analyze its complexity.
c) Implement your efficient solution using Python
demonstrate your solution
d) Provide a brief report (250 words) that explain the difference between the two solution
