Syntax: Array.hash()
Parameter: Array
Return: hash code of the array elements
示例 #1:
# Ruby code for hash() method
# declaring array
a = [18, 22, 33, nil, 5, 6]
# declaring array
b = [1, 4, 1, 1, 88, 9]
# declaring array
c = [18, 22, nil, nil, 50, 6]
# hash
puts "hash : #{a.hash()}\n\n"
# hash
puts "hash : #{b.hash()}\n\n"
# hash
puts "hash : #{c.hash()}\n\n"
输出 :
hash : -3805173463885397242
hash : -3482831379078826561
hash : 3717028813045766545
示例 #2:
# Ruby code for hash() method
# declaring array
a = ["abc", "nil", "dog"]
# declaring array
b = ["cow", nil, "dog"]
# declaring array
c = ["cat", nil, nil]
# hash
puts "hash : #{a.hash()}\n\n"
# hash
puts "hash : #{b.hash()}\n\n"
# hash
puts "hash : #{c.hash()}\n\n"
输出 :
hash : 4497783236510199145
