After reading the following, determine who is correct, Alice or Bob:
Alice and Bob want to find the value of
x=3−3−3−3−⋱22222.
Alice thinks the answer is 2. Here is her reasoning:
2=3−22=3−3−222=3−3−3−2222=3−3−3−3−22222=3−3−3−3−⋱22222.
Bob thinks it's 1. Here is his reasoning:
1=3−12=3−3−122=3−3−3−1222=3−3−3−3−12222=3−3−3−3−⋱22222.
