System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

}

bool isMatch(const char *s, const char *p) {
    int lS = strlen(s);
    int lP = strlen(p);
    vector<vector<bool> > F(lS + 1, vector<bool>(lP + 1));
    F[0][0] = true;
