Ruby Array Exercises: Create a new array from two array of integers
Write a Ruby program to create a new array of length 4 containing all their elements from two array of integers, length 2.

Ruby Code:
def check_array(a, b)
arr1 = a[0], a[1], b[0], b[1]
return arr1;
end
print check_array([1, 3], [5, 4]),"\n"
print check_array([11, 3], [5, 21])
Output:
[1, 3, 5, 4] [11, 3, 5, 21]
Flowchart:

Go to:
PREV : Write a Ruby program to create a new array of length 2 containing the middle two elements from an given array of integers of even length 2 or more.
NEXT : Write a Ruby program to swap the first and last elements of an given array of integers, length will be at least 1. Return the modified array.
