红宝石 |数组类 insert()函数

insert()是一个 Array 类方法,它通过在指定索引值处插入给定元素来返回数组。

示例 #1:

# Ruby code for insert() 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]
  
# insert
puts "insert : #{a.insert(2, 5)}\n\n"
  
# insert
puts "insert : #{b.insert(2, 4, 1, 1)}\n\n"
  
# insert
puts "insert : #{c.insert(4, 4)}\n\n"

输出 :

insert : [18, 22, 5, 33, nil, 5, 6]

insert : [1, 4, 4, 1, 1, 1, 1, 88, 9]

insert : [18, 22, nil, nil, 4, 50, 6]

示例 #2:

# Ruby code for insert() method
  
# declaring array
a = ["abc", "nil", "dog"]
  
# declaring array
b = ["cow", nil, "dog"]
  
# declaring array
c = ["cat", nil, nil]
  
# insert
puts "insert : #{a.insert(2, 5)}\n\n"
  
# insert
puts "insert : #{b.insert(2, 4, 1, 1)}\n\n"
  
# insert
puts "insert : #{c.insert(4, 4)}\n\n"

输出 :

insert : ["abc", "nil", 5, "dog"]

insert : ["cow", nil, 4, 1, 1, "dog"]

insert : ["cat", nil, nil, nil, 4]
