Ruby Array Exercises: Create an array of length 2 containing their middle elements from two given arrays of integers of length 3

Ruby Array: Exercise-15 with Solution

Write a Ruby program to create an array of length 2 containing their middle elements from two given arrays of integers of length 3.

Ruby Code:

def check_array(nums)
    if(nums.length >= 2)
		return (nums[0] + nums[1])
	end
	if(nums.length == 1)
		return nums[0];
	end
	return 0;

end
print check_array([1, 2, 5]),"\n" 
print check_array([4, 2, 3]),"\n" 
print check_array([1])

Output:

[2, 5]
[5, 8]
[2, 14]

Previous: Write a Ruby program to compute the sum of the first 2 elements of a given array of integers. If the array length is less than 2, just sum up the elements that exist, returning 0 if the length of the array is 0.
Next: Write a Ruby program to concatenate array of arrays into one.
