Ruby Array Exercises: Compute the sum of the first 2 elements of a given array of integers
Ruby Array: Exercise-14 with Solution
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.
def check_array(nums) if(nums.length >= 2) return (nums + nums) end if(nums.length == 1) return nums; end return 0; end print check_array([1, 2, 5]),"\n" print check_array([4, 2, 3]),"\n" print check_array()
