Add value to VisitedThreadSet or check if it exists
## Code Before:


class VisitedThreadSet():
    set = None

    def __init__(self):
        pass

    def load(self):
        pass

    def save(self):
        pass

    def add_thread(self):
        pass

    def check_thread_exists(self):
        pass

## Instruction:
Add value to VisitedThreadSet or check if it exists
## Code After:


class VisitedThreadSet():
    set = None

    def __init__(self):
        self.set = set()

    def load_set(self):
        pass

    def save_set(self):
        pass

    def add(self, value):
        self.set.add(str(value))

    def contains(self, value):
       if str(value) in self.set:
           return True
       else:
           return False
