hash()是一个Array类方法,它返回数组元素的哈希码
用法:Array.hash()
参数:数组
返回:数组元素的哈希码
范例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
范例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 hash:-3150640773314608759 hash:-2168259577729813344
