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)

Let's go through the code step by step to determine the output.

  1. A list q is initialized as an empty list: q = [].
  2. Several elements are appended to this list using the append method:
    • q.append(10) → q is now [10]
    • q.append(100) → q is now [10, 100]
    • q.append(1000) → q is now [10, 100, 1000]
    • q.append(10000) → q is now [10, 100, 1000, 10000]
  3. The initial state of the queue is printed: print("Initial Queue is:", q) → Output: Initial Queue is: [10, 100, 1000, 10000]
  4. The first element (10) is removed using print(q.pop(0)). After this operation, q will be: [100, 1000, 10000]
  5. The second element (100) is removed using print(q.pop(0)). Now, q will be: [1000, 10000]
  6. The third element (1000) is removed using print(q.pop(0)). Now, q will be: [10000]
  7. The current state of the queue is printed: print("After Removing elements:", q) → Output: After Removing elements: [10000]

Now, regarding the final line of code print(q), since q contains only the last remaining element, which is [10000], the output would be:

[10000]

Therefore, the final output generated by the code is:

[10000]
