Step-by-Step Solution
Solution:
Step 1: Analyze nested loops and break 2
The inner loop runs with $j from 0 to 2. When $j == 1,break 2;exits both loops immediately.Step 2: Trace output before break
Only when $j == 0, echo "$i$j "; prints "00 ". Then at $j == 1, break 2 stops all loops.Final Answer:
00 -> Option BQuick Check:
Break 2 exits both loops, output = 00 [OK]
Quick Trick: Break 2 exits two loops immediately [OK]
Common Mistakes:
- Expecting all loop outputs before break
- Confusing break with continue
- Ignoring break level count
