如何使用Ruby将对象推送到数组x次？

如果array = [1,2,3,4,5],我怎样才能将数字6,x的次数推到数组中.

array.push(6) * x

当我运行类似的东西时,它会返回被推送6次x的整个数组.将括号括在push * x周围会使我的代码无效,有什么建议吗？

例：

array.push(6) "2 times" => [1,5,6,6]

解决方法

是的,您可以使用 Array#fill方法.

array = [1,5]
array.fill(12,array.size,4)
# => [1,12,12]

说明

Suppose you have an array a = [1,3]. Now a.size will give you 3,where last index is 2. So,when you are using a.size with #fill,then you are telling to start pushing object from 3 to some n number of times.
