How to check if Two Arrays are Equal in Ruby - Step by Step Examples
How to check if Two Arrays are Equal in Ruby ?
Answer
To check if two arrays are equal in Ruby, you can use the ==
operator for arrays with the same elements and manually compare elements for arrays with different elements.
✐ Examples
1 Arrays with Same Elements
In this example,
- We create two arrays named
arr1
andarr2
with the same elements. - We then use the
==
operator to check if the arrays are equal and store the result in the variableequal1
. - The
==
operator checks if two arrays have the same elements in the same order. - Finally, we print the value of
equal1
to the console.
Ruby Program
arr1 = [1, 2, 3]
arr2 = [1, 2, 3]
equal1 = arr1 == arr2
puts "Arrays are equal: #{equal1}"
Output
Arrays are equal: true
2 Arrays with Different Elements
In this example,
- We create two arrays named
arr3
andarr4
with different elements. - We then manually compare each element of both arrays and store the result in the variable
equal2
. - If all elements are equal,
equal2
is set totrue
; otherwise, it's set tofalse
. - Finally, we print the value of
equal2
to the console.
Ruby Program
arr3 = [1, 2, 3]
arr4 = [3, 2, 1]
equal2 = true
arr3.each_with_index do |elem, index|
unless elem == arr4[index]
equal2 = false
break
end
end
puts "Arrays are equal: #{equal2}"
Output
Arrays are equal: false
