Ruby - Arrays

What is the output of the following Ruby code?

arr = [3, 1, 4, 2]
sorted_arr = arr.sort
reversed_arr = sorted_arr.reverse
puts reversed_arr.inspect

A[1, 2, 3, 4]

B[3, 1, 4, 2]

C[4, 3, 2, 1]

D[2, 4, 1, 3]

Step-by-Step Solution

Solution:

Step 1: Sort the original array
Calling arr.sort returns a new array sorted ascending: [1, 2, 3, 4].
Step 2: Reverse the sorted array
Calling sorted_arr.reverse flips the order to [4, 3, 2, 1].
Final Answer:
[4, 3, 2, 1] -> Option C
Quick Check:
sort then reverse = descending order [OK]

Quick Trick: Sort then reverse = descending order [OK]
