"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 each character of the two strings. For each matching character, add one point to user_score. Upon a mismatch, end the loop. Sample output with inputs: 'rrgbryybgy' 'rrgbbrybgy' user score: 4.
