Problem Solution:

In this program, we will create an array of integer elements. Then we will remove all "nil" elements from the array using the compact() method.

Program/Source Code:

The source code to remove all "nil" elements from the array is given below. The given program is compiled and executed successfully.

# Ruby program to remove all 
# "nil" elements from the array

arr = [10,21,30,nil,41,nil,50];

print "Array elements: \n",arr,"\n";

arr = arr.compact();

print "Array elements: \n",arr,"\n";

Output:

Array elements: 
[10, 21, 30, nil, 41, nil, 50]
Array elements: 
[10, 21, 30, 41, 50]

Explanation:

In the above program, we created an array arr with some elements. Then we removed all "nil" elements from the array using the compact() method. After that, we printed the updated array.
