Question

what is the expected output of the following segment of code?

dq = Deque()

dq.push_back('M')

dq.push_back(' ')

l = ['A', 'L', 'E', 'S', 'T', 'E']

for i in l:

→ if ord(i) % 3 == 0:

→ → dq.push_back(i)

→ elif ord(i) % 5 == 0:

→ → dq.push_front(i)

→ → dq.push_back(i)

→ elif ord(i) % 4 == 0:

→ → dq.push_back(i)

→ else:

→ → dq.peek_front()

→ → dq.push_front('X')

→ → dq.push_back('R')

dq.push_front(dq.peek_back())

dq.pop_back()

print(dq)

Answer 1

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU
Output

deque(['E', 'X', 'A', 'M', ' ', 'A', 'L', 'E', 'R', 'T'])

The above is not compatible with python, so I made same program that would be compatible in python

from collections import deque  

dq = deque()
dq.append('M')
dq.append(' ')
l = ['A', 'L', 'E', 'S', 'T', 'E']
for i in l:
    if ord(i) % 3 == 0:
        dq.append(i)
    elif ord(i) % 5 == 0:
        dq.appendleft(i)
        dq.append(i)
    elif ord(i) % 4 == 0:
        dq.append(i)
    else:
        dq[0]
        dq.appendleft('X')
        dq.append('R')
dq.appendleft(dq[len(dq)-1])
dq.pop()
print(dq)
