j += 1
i += 1What is the output of this code?
medium📝 Predict Output Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Trace outer loop iterations
i starts at 1 and runs while i <= 2, so i = 1 and i = 2.Step 2: Trace inner loop iterations for each i
For each i, j runs from 1 to 3, printing i and j each time.Final Answer:
1 1\n1 2\n1 3\n2 1\n2 2\n2 3 -> Option CQuick Check:
Inner loop prints 3 times per outer loop iteration [OK]
Quick Trick: Inner loop runs fully for each outer loop iteration [OK]
Common Mistakes:
MISTAKES- Only printing inner loop once
- Mixing up i and j values
- Stopping loops too early
