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。
Syntax: s1.name.intersection(s2.name)
Parameters: The function does not takes any parameter.
Return Value: It returns a new set that contains the common elements in both the sets.
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}
