# Ruby program to delete suffix substring 
# from the given string

str = "Hello, how are you";
substr = "are you";

print "Str before deletion: ",str,"\n";

str = str.delete_suffix(substr);

print "Str after deletion: ",str,"\n";

Output:

Str before deletion: Hello, how are you
Str after deletion: Hello, how 

Explanation:

In the above program, we created two strings str, substr that are initialized with "Hello, how are you", "are you" respectively. Then we used the delete_suffix() function to remove suffix substring and return the updated string. After that, we printed the updated string.
