How to check array elements (Ruby)?

Question

ruby

Hello, you need to iterate over the elements of the array, and if the element on the right is greater than the element on the left, display a message that this element is greater than the previous one. My program correctly detects only the first two elements correctly.

a=[11,22,31,224,44,10,20].each_with_index { |val,index| 
   if val[index] > val[index-1]
   	puts "Элемент #{index} больше левого соседа" 
   else 
   	puts "Hello"
   end
}

Please tell me what needs to be corrected.

Answer 1

a = [11, 22, 31, 224, 44, 10, 20]

a.each_index do |index| 
  if a[index] > a[index-1]
    puts "Элемент #{index} больше левого соседа" 
  else 
    puts "Hello"
  end
end

Answer 2

[11,22,31,224,44,10,20].each_with_index { |val,index| puts "Элемент #{index} больше левого соседа" if val[index] > val[index-1]}

Yes, that should also work.
