Problem Solution:

In this program, we will create a hash collection. Then we will print the original and inverted hash collection, here we will invert key/value to each other.

Program/Source Code:

The source code to print the inverted hash collection is given below. The given program is compiled and executed on Windows 10 Operating System successfully.

# Ruby program to print the 
# inverted hash collection

student = {"101" => "Amit", "102" => "Arun", "103" => "Sumit"};

print "Original Hash collection: \n",student;
print "\nInverted hash collection: \n",student.invert();

Output:

Original Hash collection: 
{"101"=>"Amit", "102"=>"Arun", "103"=>"Sumit"}
Inverted hash collection: 
{"Amit"=>"101", "Arun"=>"102", "Sumit"=>"103"}
