Submitted by Nidhi, on January 05, 2022

Problem Solution:

In this program, we will create a string and then we will remove the prefix substring from the created string using the delete_prefix() function and return the result.

Program/Source Code:

The source code to delete prefix substring from the given string is given below. The given program is compiled and executed successfully.

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

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

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

str = str.delete_prefix(substr);

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

Output:

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

Explanation:

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