Ruby - Enumerable and Collection Processing

What will be the output of this Ruby code?

words = ["apple", "banana", "cherry", "date"]
filtered = words.reject { |w| w.length > 5 }
p filtered

A["banana", "cherry"]

B["apple", "banana", "cherry", "date"]

C[]

D["apple", "date"]

Step-by-Step Solution

Solution:

Step 1: Understand the reject condition
Reject words where length is greater than 5, so remove words longer than 5 characters.
Step 2: Identify words kept
"banana" and "cherry" have length 6 and 6, so removed; "apple" (5) and "date" (4) remain.
Final Answer:
["apple", "date"] -> Option D
Quick Check:
reject length > 5 = keep length ≤ 5 [OK]

Quick Trick: Reject removes elements matching condition, keeps others [OK]
