红宝石 |设置交点()函数

intersection()是 Ruby 中的一个内置方法,它返回一个集合,其中包含两个集合中的公共元素。如果没有公共元素,则返回一个空集。

示例 1

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


Ruby
# Ruby program to illustrate the intersection method
  
# requires the set
require "set"
  
s1 = Set[1, 2, 4]
s2 = Set[6, 5, 3]
  
# method used
s3 = s1.intersection(s2)
  
# Prints the s3
puts s3


输出

Set: {1, 2}
