Step-by-Step Solution
Solution:
Step 1: Loop ranges
Rows and columns start at 1 and go up to 4 inclusive.Step 2: Inner loop variable reset
Reset 'j' to 1 at the start of each outer loop iteration.Step 3: Correct increments and print
Increment 'j' inside inner loop, 'i' inside outer loop, print product with space, and print newline after inner loop.Final Answer:
i = 1 while i <= 4: j = 1 while j <= 4: print(i * j, end=' ') j += 1 print() i += 1 correctly implements this logic.Quick Check:
Reset inner variable and print product with correct loops [OK]
Quick Trick: Reset inner loop variable each outer iteration [OK]
Common Mistakes:
MISTAKES- Incrementing outer loop variable inside inner loop
- Using addition instead of multiplication
- Starting loops from 0 instead of 1
- Not printing newline after each row
