}What is the output of this Kotlin code?
medium📝 Predict Output Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Identify loop values with downTo and step
Start at 10, count down to 2, stepping by 4 means subtract 4 each time: 10, 6, 2.Step 2: Confirm loop stops at or above 2
Next step after 2 would be -2 which is below 2, so loop ends.Final Answer:
10 6 2 -> Option AQuick Check:
downTo with step 4 outputs 10 6 2 [OK]
Quick Trick: Count down subtracting step until reaching end value [OK]
Common Mistakes:
MISTAKES- Including numbers below end value
- Confusing step direction
- Printing spaces instead of concatenated output
