Removing multiple elements from array by index in Ruby [duplicate]

Question

I have an array. For example,

x = [1,2,3,4,5]

I know the command

x.delete_at(i)

will delete the element at index i from the array. But from what I've read, it can only handle one argument.

Let's say I have a variable that stores the indexes I wish to remove from x. For example,

y = [0,2,3]

My question: Is it possible to remove multiple elements from an array using another array that stores in the indexes you wish to delete at?

In essence, something like

x.delete_at(y)

Thanks! :)

Answer 1

You can use reject with with_index:

x.reject.with_index { |e, i| y.include? i } #=> [2, 5]
