Ruby - String Operations

Identify the issue in the following Ruby code snippet:

str = "testing"
puts str[3, -2]

AIndex 3 is out of range for the string

BNegative length in slicing is invalid and causes an error

CThe code correctly prints 'ti'

DThe code prints an empty string

Step-by-Step Solution

Solution:

Step 1: Understand slicing parameters
In Ruby, str[start, length] expects length to be a non-negative integer.
Step 2: Analyze the code
The code uses a negative length (-2), which is invalid and causes the method to return nil or raise an error.
Final Answer:
Negative length in slicing is invalid and causes an error -> Option B
Quick Check:
Negative length slicing is not allowed [OK]

Quick Trick: Length in str[start, length] must be non-negative [OK]
