Question

Given the following code, what would the output on the final line be?

# implementing Queue using List:
q=[]
q.append(10)
q.append(100)
q.append(1000)
q.append(10000)
print("Initial Queue is:",q)
print(q.pop(0))
print(q.pop(0))
print(q.pop(0))
print("After Removing elements:",q)

Answer 1

To analyze the output of the provided code step by step:

1. A list `q` is initialized as an empty list: `q=[]`.
2. Four elements are appended to the list:
- `q.append(10)` makes the list: `[10]`
- `q.append(100)` makes the list: `[10, 100]`
- `q.append(1000)` makes the list: `[10, 100, 1000]`
- `q.append(10000)` makes the list: `[10, 100, 1000, 10000]`
3. The initial queue is printed: `Initial Queue is: [10, 100, 1000, 10000]`.
4. The first call `q.pop(0)` removes and returns the first element (10):
- After this call, the list becomes: `[100, 1000, 10000]`.
5. The second call `q.pop(0)` removes and returns the first element (100):
- After this call, the list becomes: `[1000, 10000]`.
6. The third call `q.pop(0)` removes and returns the first element (1000):
- After this call, the list becomes: `[10000]`.
7. Finally, the remaining elements in the queue are printed: `After Removing elements: [10000]`.

Thus, the final output of the last print statement will be:
```
[10000]
```

So the correct response is:
```
[10000]
```
