What is the output of this Ruby code?

text = "hello 123 world 456"
matches = text.scan(/\d+/)
puts matches.inspect

A["123", "456"]

B["hello", "world"]

D[]

Step-by-Step Solution

Solution:

Step 1: Analyze the regex pattern
The pattern /\d+/ matches sequences of digits, not individual digits.
Step 2: Apply scan to the string
It finds "123" and "456" as two separate matches.
Final Answer:
["123", "456"] -> Option A
Quick Check:
scan with /\d+/ returns digit groups = D [OK]

Quick Trick: scan with /\d+/ returns digit groups, not single digits [OK]
