Ruby 数组类的hash()函数 hash()是一个数组类的方法,用于返回数组元素的哈希代码。 语法。Array.hash() 参数。数组 返回:数组元素的哈希代码 例子 #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"RubyCopy 输出: hash : -3805173463885397242 hash : -3482831379078826561 hash : 3717028813045766545 RubyCopy 例子 #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"RubyCopy 输出: hash : 4497783236510199145 hash : -3150640773314608759 hash : -2168259577729813344 RubyCopy
