Untitled- Edited ST Insert Table Chart Text Shape Media Comment Co Collaborate 125% Zoom Bod Do the banner question from lab 3 but now, the banner must be printed in a function called printBanner. This function takes no input and returns nothing It prints the banner with a message as shown in the output below (similar message as in lab 3 banner). The function prompts the user to enter their first name, which is then printed in the banner. You may assume that the line of stars has 50 stars in it. Sample Input: Enter your first name: Dumbledore Output: Font Hel Reg Chara Welcome to week 7 lab Dumbledore Alignn @ e.*eee* e*eeeeeee.eeeeee e Spa Lines
