A built-in Ruby function called `divide()`

returns a set of subsets. It takes a condition specified by a **single-element subset**. Ruby’s `set`

class provides a useful way for splitting sets into subsets according to user-defined criteria. Users can divide the set according to arbitrary criteria by utilizing blocks, allowing for flexible data processing and analysis.

The following is the syntax of the built-in Ruby function `divide()`

:

s1.divide { |i, j| condition }

The `condition`

under which the set is to be subdivided into a set of subsets is taken by the function `divide()`

.The variables `i`

and `j`

are block parameters used in the block passed to the `set.divide()`

method.

It creates a new set by duplicating the original set and removes every element that appears in the given

Let’s explore how the `set.divide()`

function works in Ruby with the help of a code example:

# Requires the set classrequire "set"# Creates a sets1 = Set.new([8, 5, 4, 11, 14, 7, 20, 17])puts "Original Set:"puts s1.to_a# Divides the set into subsets based on a conditionresult = s1.divide { |i, j| (i - j).abs == 2 }puts "\nDivided Sets:"result.each_with_index do |subset, index|puts "Subset #{index + 1}: #{subset.to_a}"end

**Line 2:**We use`require`

to include the`set`

class in our program.**Line 5:**We create a set`s1`

containing various numbers.**Line 8:**We print the original set to the console using the`to_a`

method, which converts the set to an array for display.**Line 11:**We use the`set.divide()`

method to divide the set into subsets based on a condition provided in the block. In this example, the condition is that the absolute difference between elements in a subset should be 2.**Lines 13–16:**We print the divided sets. Each subset is printed with a label indicating its index.

The `divide()`

function in Ruby's `set`

class provides a convenient way to partition sets into subsets based on specified conditions, offering flexibility in data manipulation and analysis.
