medium📝 Predict Output Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Identify substring positions in 'abracadabra'
Look for 'ra' in the string: 'abracadabra'. The substring 'ra' starts at index 3 and 10.Step 2: Confirm output of strfind
strfindreturns starting indices of matches, so output is [3 10].Final Answer:
[3 10] -> Option AQuick Check:
Positions of 'ra' = [3 10] [OK]
Quick Trick: Count string indices carefully for strfind output [OK]
Common Mistakes:
- Counting indices starting at 0 instead of 1
- Confusing substring length with position
- Expecting logical output instead of indices
