红宝石 |设置divide()函数

divide()是 Ruby 中的一个内置方法，它返回一组集合。它根据块给出的条件进行划分。如果它们不满足给定条件，则将它们分成单个元素。

Syntax: s1.divide(condition)

Parameters: The function takes the condition on which the set is to be divided into sets of set.

Return Value: It returns a new set built by duplicating the set, removing every element that appears in the given enumerable object.

示例 1 ：

# Ruby program to illustrate the divide method 
  
# requires the set 
require "set"
  
s1 = Set[8, 5, 4]
  
  
# divide method used
puts s1.divide { |i,j| (i - j).abs == 3 }

输出：

Set: {#Set: {8, 5}, #Set: {4}}

示例 2 ：

# Ruby program to illustrate the divide method 
  
# requires the set 
require "set"
  
s1 = Set[16, 8, 3, 5, 2]
  
# divide method used
puts s1.divide { |i,j| (i - j)%2 == 0 }

输出：

Set: {#Set: {16, 8, 2}, #Set: {3, 5}}
