Answer:
Prob because you were giving away free points or broke the rules.
For a string length of 1 there are 2 possible strings (2^1)
for a string length of 2 there are 4 possible strings (2^2)
for a string length of 3 there are 8 possible strings (2^3)
So, for string length of 7 there are 128 possible strings (2^7)
Not sure but I think it is 3. If you get it wrong I am so sorry.
