Question

the following block of code in a video game is intended to keep track of the name of the high scorer. in the code, number is the score of the current player at the end of the game, highscore is the previous high score, scoreboard is the list that contains the names of previous players in order of their score (with the entry at index 1 containing the name of the current high scorer). image of code block: if number > highscore, then remove scoreboard, 1; name ← input; insert scoreboard, 1, name; else display \sorry, try again\ which of the following best describes what this fragment of code does when the current player achieves a score which is higher than the current high score? options: 1. the current players name is inserted in the first position in the list scoreboard and all other names remain in the same position in the list. 2. the current players name is inserted in the first position in the list scoreboard, the name of the previous high scorer is deleted and all other names remain in the same position in the list. 3. the current players name is inserted in the first position in the list scoreboard and all other names are shifted one place lower in the list. 4. the current players name is inserted in the first position in the list scoreboard, the name of the previous high scorer is deleted and all other names are shifted one place lower in the list.

Explanation:

1. Analyze the code steps when number > highscore:

• First, REMOVE scoreboard, 1 (removes the previous high - scorer's name at index 1).
• Then, name ← INPUT (gets the current player's name).
• Then, INSERT scoreboard, 1, name (inserts the current player's name at index 1).
• When we remove the element at index 1 and then insert a new element at index 1, the other elements (those with indices greater than 1 originally) will shift one place lower in the list. Also, the previous high - scorer's name (at index 1) is deleted.

1. Evaluate each option:

• Option 1: Says all other names remain in the same position, which is wrong because after removal and insertion, other names shift.
• Option 2: Says all other names remain in the same position, which is wrong.
• Option 3: Does not mention the deletion of the previous high - scorer's name, which is part of the code (REMOVE scoreboard, 1).
• Option 4: Correctly states that the current player's name is inserted in the first position, the previous high - scorer's name is deleted, and all other names are shifted one place lower.

Answer:

The current player's name is inserted in the first position in the list scoreboard, the name of the previous high scorer is deleted and all other names are shifted one place lower in the list. (The option corresponding to this description)
