How to Iterate Over an Array in Reverse Order in Ruby - Step by Step Examples
How to Iterate Over an Array in Reverse Order in Ruby ?
Answer
To iterate over an array in Ruby in reverse order, you can use the reverse_each
method or a for
loop starting from the last index to the first index.
✐ Examples
1 Iterate Over Integer Array in Reverse with reverse_each Method
In this example,
- We create an integer array named
numbers
with some values. - We use the
reverse_each
method to iterate over each element of the array in reverse order.
Ruby Program
numbers = [1, 2, 3, 4, 5]
numbers.reverse_each do |number|
puts number
end
Output
5 4 3 2 1
2 Iterate Over String Array in Reverse with for Loop
In this example,
- We create a string array named
fruits
with some values. - We use a
for
loop starting from the last index to iterate over each element of the array in reverse order.
Ruby Program
fruits = ["apple", "banana", "cherry"]
(fruits.length - 1).downto(0) do |i|
puts fruits[i]
end
Output
cherry banana apple
