Write a Ruby program to check whether first and the last element are the same of a given array of integers. The array length must be 1 or more.

Ruby Code:

def check_array(nums)
   return (nums.length >= 1 && nums[0] ==  nums[nums.length-1])
end
print check_array([1, 2, 7]),"\n"
print check_array([3, 1, 2, 3]),"\n"
print check_array([14, 7, 1, 2, 3])

Output:

false
true
false
