## Ruby Array: Exercise-30 with Solution

Write a Ruby program to find the difference between the largest and smallest values of a given array of integers of length 1 or more.

**Ruby Code:**

```
def check_array(nums)
max = nums[0];
min = nums[0];
nums.each do |item|
if(item > max)
max = item;
elsif(item < min)
min = item
end
end
return (max-min)
end
print check_array([3, 4, 5, 6]),"\n"
print check_array([3, 4, 5]),"\n"
print check_array([3, 4])
```

Output:
