PseudoCode for the Longest Substring Problem
int maxLength
int maxStart
int start
some set S
for each character C in the input string
check if this character is a repeated character (look for C in S)
if it is, repeat this:
look at the first character in my candidate substring.
remove that character from the front of the substring. (increment start)
remove that character also from S.
