Problem Solution:

In this program, we will create an array of integers then we will add an element in the array at the beginning using unshift() method.

Program/Source Code:

The source code to add an element in the array at the beginning is given below. The given program is compiled and executed successfully.

# Ruby program to add an element 
# in array at beginning

arr = [10,20,30,20,50,30];

result = arr.unshift(80);

print "Result: \n",result,"\n";

Output:

Result: 
[80, 10, 20, 30, 20, 50, 30]

Explanation:

In the above program, we created an array arr with some elements. Then we used unshift() method. The unshift() method is used to add an element at the beginning of the array. After that, we print the updated array.
