将数组值插入另一个数组的随机位置-Insertarrayvaluesintorandompositionsofanotherarray

This will probably work:

这可能会奏效：

a = [1, 2, 3]
b = [:foo, :bar, :baz]

b.each_with_object(a.dup) { |e, ary| ary.insert(rand(0..ary.size), e) }
#=> [:baz, 1, 2, :foo, :bar, 3]

• dup creates a copy of a that is passed as ary into the block, along with each of b's elements
• dup创建一个作为ary传递到块中的副本，以及每个b的元素
• rand returns a random index between 0 (beginning of array) and ary.size (end of array)
• rand返回0（数组的开头）和ary.size（数组的结尾）之间的随机索引
• insert inserts the current element at the given index
• insert将当前元素插入给定索引
• each_with_object returns the copied array with the randomly inserted elements
• each_with_object返回带有随机插入元素的复制数组

Here's another way:

这是另一种方式：

def stuff_randomly(a,b)
  sz_a  = a.size
  cpy_a = a.dup
  (sz_a+b.size).times.to_a.shuffle.map do |i|
    (i
