Ruby - Enumerable and Collection Processing

What will be the output of this Ruby code?

values = [4, 6, 8]
result = values.inject(2) { |acc, num| acc + num }
puts result

A20

B18

C24

D16

Step-by-Step Solution

Solution:

Step 1: Understand initial value
The inject method starts with an initial accumulator value of 2.
Step 2: Perform accumulation
It adds each element of the array to the accumulator: 2 + 4 = 6, then 6 + 6 = 12, then 12 + 8 = 20.
Final Answer:
20 -> Option A
Quick Check:
Sum with initial 2: 2 + 4 + 6 + 8 = 20 [OK]

Quick Trick: Add elements starting from initial value [OK]
