medium📝 Predict Output Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Trace the loop
Start with num=1, then multiply by 2 each iteration: 2, 4, 8, 16.Step 2: Check the break condition
When num becomes 16, it is greater than 10, so the loop breaks.Step 3: Print the value
The printed value is 16.Final Answer:
16 -> Option BQuick Check:
Loop breaks when num > 10, last num is 16 [OK]
Quick Trick: Multiply until condition met, then break [OK]
Common Mistakes:
MISTAKES- Stopping at 10 instead of the first value greater than 10
- Printing the value before the break
- Misunderstanding the loop multiplication
