Ruby Array Exercises: Compute the sum of the first 2 elements of a given array of integers

Last update on December 21 2024 10:15:18 (UTC/GMT +8 hours)

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.

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:

3
6
1

Previous: Write a Ruby program to find the larger between the first and last elements of a given array of integers and length 3. Replace all the other values to be that value. Return the changed array.
Next: Write a Ruby program to create an array of length 2 containing their middle elements from two given arrays of integers and length 3.
