The dot product of two vectors a = [a₁, ª₂,..., an] and b=[b₁,b2,...,bn can be defined algebraically as a∙b=a₁b₁+a₂b2+...+anbn Given the following two vectors represented using Python lists: vector1 = [1,-5, 6, 11, −13, 17] vector2 = [-10, 8, 14, -7, -3, 19] Write a program that calculates and prints the dot product of these two vectors. Notes: • The output must be in the format shown in the example, including the format of the prompt, and all spaces and punctuation. • Your solution must use a while loop. • You may assume both vectors are the same length. For example: Test #Execute program The dot product of [1, -5, 6, 11, -13, 17] and [-10, 8, 14, -7, -3, 19] is 319. Result Complete the following program which prompts the user to enter their first name and then their surname. The program will generate a 5 letter username consisting of the first letter of the user's first name and the first 4 letters of the user's surname. If the user's surname is less than 4 letters in length, the program will add the required number of "*" characters to the end of the username to ensure it has a length of 5. Notes: • The output must be in the format shown in the example, including the format of the prompt, and all spaces and punctuation. For example: Input Result Damir Please enter your first name: Damir Azhar Please enter your surname: Azhar Your username is: DAzha John Please enter your first name: John Doe Please enter your surname: Doe Your username is: JDoe* The dot product of two vectors a = [a₁, ª₂,..., an] and b=[b₁,b2,...,bn can be defined algebraically as a∙b=a₁b₁+a₂b2+...+anbn Given the following two vectors represented using Python lists: vector1 = [1,-5, 6, 11, −13, 17] vector2 = [-10, 8, 14, -7, -3, 19] Write a program that calculates and prints the dot product of these two vectors.
