示例 1 :
# Ruby program to illustrate
# the intersect method
# requires the set
require "set"
s1 = Set[16, 8, 3, 5, 2]
s2 = Set[18, 17, 2]
# intersect method used
puts s1.intersect?(s2)
输出:
true
示例 2 :
# Ruby program to illustrate
# the intersect method
# requires the set
require "set"
s1 = Set[16, 8]
s2 = Set[18, 17, 56]
