medium📝 Predict Output Q5 of 15

Ruby - Arrays

arr = [5, 10, 15, 20, 25]
slice = arr[2...5]
puts slice.inspect

A[15, 20, 25]

B[15, 20]

C[10, 15, 20]

D[10, 15, 20, 25]

Step-by-Step Solution

Solution:

Step 1: Understand the range 2...5
The three-dot range excludes the end index 5, so it includes indices 2, 3, and 4.
Step 2: Extract elements at indices 2, 3, and 4
These elements are 15, 20, and 25 respectively.
Final Answer:
[15, 20, 25] -> Option A
Quick Check:
Three-dot range excludes end index, so arr[2...5] = [15, 20, 25] [OK]

Quick Trick: Three-dot range excludes the last index [OK]
