Ruby - Find the Minimum Element in an Array

1. Introduction

Arrays are foundational data structures in computer programming, and often, we need to identify certain specific elements within them, such as the smallest value. Ruby, with its expressive syntax, makes it easy to find the minimum element in an array. In this post, we will explore how to find the minimum element in an array using Ruby.

2. Program Steps

1. Define or initialize an array.

2. Utilize the min method of the array to ascertain its minimum element.

3. Display the minimum element to the console.

3. Code Program

# Define an array
numbers = [34, 12, 89, 53, 3, 67]
# Determine the minimum element in the array
min_element = numbers.min
# Print the minimum element
puts "The minimum element in the array is: #{min_element}"

Output:

The minimum element in the array is: 3

Explanation:

1. numbers = [34, 12, 89, 53, 3, 67]: Here, we set up an array named numbers containing various integers.

2. numbers.min: The min method is called upon the array, returning the smallest value contained within it.

3. puts: We use this command to print the derived result onto the console.

Thanks to Ruby's powerful built-in methods, identifying the minimum element in an array becomes a straightforward task.
