What will be the output of this pseudocode simulating GPU task queue?

queue = ["render", "compute", "display"]
task = queue.pop(0)
print(task)
print(queue)

AError: pop method not found
Bdisplay ['render', 'compute']
Ccompute ['render', 'display']
Drender ['compute', 'display']
Step-by-Step Solution
Solution:
  1. Step 1: Understand pop(0) on the list

    pop(0) removes and returns the first element, which is "render".
  2. Step 2: Print the removed task and remaining queue

    First print outputs "render", second print outputs the list without "render": ['compute', 'display'].
  3. Final Answer:

    render ['compute', 'display'] -> Option D
  4. Quick Check:

    pop(0) removes first item = render [OK]
Quick Trick: pop(0) removes first item from list [OK]
Common Mistakes:
MISTAKES
  • Assuming pop removes last item by default
  • Confusing list order after pop
  • Thinking pop method is invalid
