How to check if Two Arrays have Same Elements (Regardless of Order) in Ruby

How to check if Two Arrays have Same Elements (Regardless of Order) in Ruby ?

To check if two arrays have the same elements regardless of order in Ruby, you can sort both arrays and then compare them element by element.

In this example,

We create two arrays named arr1 and arr2 with the same elements but in different order.
We sort both arrays using the sort method.
We then define a method arrays_equal that checks if the sorted arrays are equal.
Finally, we call arrays_equal to compare the arrays and print the result.

def arrays_equal(arr1, arr2)
  arr1.sort == arr2.sort
end

arr1 = [1, 2, 3]
arr2 = [3, 1, 2]

puts arrays_equal(arr1, arr2)

true

In this example,

We create two arrays named arr3 and arr4 with different elements.
We sort both arrays using the sort method.
We then define a method arrays_equal that checks if the sorted arrays are equal.
Finally, we call arrays_equal to compare the arrays and print the result.

def arrays_equal(arr1, arr2)
  arr1.sort == arr2.sort
end

arr3 = [1, 2, 3]
arr4 = [4, 5, 6]

puts arrays_equal(arr3, arr4)

false
