In a modify task you take code that has already been started and adapt it so that it does what it should.

A school needs a system that automatically generates a username for each student. A programmer has started the code, but left gaps where the string slicing and the case conversion should go. Every gap is marked with question marks:

print("Enter student first name:")
first_name = input()

print("Enter student last name:")
last_name = input()

first_initial = first_name[????]

username = ???????

print("Generated username: " + ???????)

The editor starts you off with this code. It does not run as it stands: Python stops at the first line of question marks.

Your task

Modify the program so that it:

• converts both names to lower case,
• takes the first character of the first name and concatenates it with the full last name,
• outputs the generated username after the text Generated username: .

Keep the two questions exactly as they are. The case conversion can go anywhere before the username is built, as long as both names end up in small letters.

The output

The two questions first, worded exactly like this:

Enter student first name:
Enter student last name:

Then one line, where USERNAME is the first letter of the first name followed by the whole last name, all in lower case:

Generated username: USERNAME

Example

Input:

Ada
Lovelace

Output:

Enter student first name:
Enter student last name:
Generated username: alovelace

Input:

ALAN
TURING

Output:

Enter student first name:
Enter student last name:
Generated username: aturing

Anything else in the last name stays in: Tim and Berners-Lee give tberners-lee.
