Question

4.10.1: Simon says. "Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement. Assume simonPattern and userPattern are always the same length. Ex: The following patterns yield a userScore of 4: simonPattern: RRGBRYYBGY userPattern: RRGBBRYBGY

Answer 1

Answer:

for  i  in range(0,10):

   if SimonPattern[i] == UserPattern[i]:

       score = score + 1

       i = i + 1

   else:

       break

if i == 9:

   score = score + 1    

print("Total Score: {}".format(score))

Explanation:

This for loop was made using Python. Full code attached.

• For loop requires a range of numbers to define the end points. For this Simon Says game, we are talking about 10 characters, so that must be the range for the for loop: from 0 to 10.
• Conditional if  tests if Simon pattern matches User's one characheter by one and add point for each match.
• Break statement is ready to escape the for loop at first mismatch.
• As we are starting from index 0, if the users matched all the characters correctly, then we need to add 1, otherwise the maximun score would be 9 and it should be 10.
