红宝石 |设置脱节？函数

脱节？是 Ruby 中的一个内置方法，如果集合和给定集合没有共同元素，则返回 true。

Syntax: s1.disjoint?(s2)

Parameters: The function does not takes any parameter.

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 disjoint? method 
   
# requires the set 
require "set"
   
s1 = Set[1, 2, 4]
s2 = Set[1, 2, 3] 
   
# difference method used
s3 = s1.disjoint?(s2)
   
# Prints the s3 
puts s3

输出：

false

示例 2 ：

# Ruby program to illustrate the disjoint? method 
   
# requires the set 
require "set"
   
s1 = Set[8, 5, 4]
s2 = Set[1, 2, 3] 
   
# difference method used
s3 = s1.disjoint?(s2)
   
# Prints the s3 
puts s3

输出：

true
