Give a theta analysis of the time efficiency of the following code fragments.

A) n = int(input(enter n: ))

for i in range(n)

x = 2 * n

while x > 1:

x = x / 2

B) n = int(input(enter n: ))

total = 0

for i in range(n)

for j in range(10000):

total += j

print(total)

C) n = int(input(enter n: ))

total = 0

for i in range(2 * n)

for j in range(i, n):

total += j

for j in range(n):

total += j

print(total)

WILL RATE!
