Python - For Loop
Which of these best describes the total number of iterations in a nested loop where outer loop runs 3 times and inner loop runs 4 times?
Which of these best describes the total number of iterations in a nested loop where outer loop runs 3 times and inner loop runs 4 times?
easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate iterations of outer and inner loops
The outer loop runs 3 times, and for each outer iteration, the inner loop runs 4 times.Step 2: Multiply to find total iterations
Total iterations = 3 (outer) * 4 (inner) = 12.Final Answer:
12 iterations total -> Option AQuick Check:
Total iterations = outer * inner = 12 [OK]
Quick Trick: Multiply outer and inner loop counts for total iterations [OK]
Common Mistakes:
MISTAKES- Adding instead of multiplying loop counts
- Confusing outer and inner loop counts
- Ignoring inner loop iterations
