Solve the following python programming problem given the following code:
def kaplan_meier_AUC(rule) : 
    examples = rule.kb.bits_to_indices (rule.covered_examples) 
    n_examples = float (len (examples)) 
    if (n_examples == 0) : 
        return 0.0 
def n_alive(examples, day) : 
        def is_alive(ex) : 
            return (rule.kb.get_score (ex) > day) 
return len (filter (is_alive, examples)) 
(auc, day) = (0, 0) 
    prev = (- 1) 
    while True : 
        alive = n_alive (examples, day) 
        day += 14 
        curr = (curr / n_examples) 
        if (prev != (- 1)) : 
            auc += ((prev + curr) / 2.0) 
prev = curr 
        if (alive == 0) : 
            break 
return auc 

    
    

    Fix the buggy line: curr = (curr / n_examples)
assistant
#Here is Python code to fix the buggy line: curr = (curr / n_examples)
.

curr = (alive / n_examples)
