 # 5.3. Flip Bit to Win
 
-> You have an integer and you can flip exactly one bit from a 0 to a 1. Write code to find the length of the longest sequence of 1s you could create. Input: 1775, or  11011101111, Output: 8

 Brute force idea: find all 0s, flip all of them, count all 1s sequences (how?), output max.
