Question

Justify each answer.

Write pseudocode for an algorithm that interchanges the values of the variables m and n, using only assignments (assigning values to variables).
Arrange the functions (1.5)ⁿ, n¹⁰⁰, (log₂n)³, 10ⁿ, n!, and n⁹⁹so that each function is big-O of the next function.
Give a big-O estimate for the following algorithm:

count = array of k + 1 zeros

for x in input do

count[key(x)] + = 1

end for

total = 0

for i in 0,1,...k do

count[i], total = total, count[i] + total

end for

output = array of the same length as input

for x in input do

output[count[key(x)]] = x

count[key(x)] + = 1

end for return output
