WebApr 12, 2024 · On the other hand, HashMap is not thread-safe and can cause problems if accessed by multiple threads at the same time. Hashtable does not allow null values for keys or values, whereas HashMap allows null values for both keys and values. HashMap is generally faster than Hashtable because it is not synchronized. WebThe iterative version has a control variable i, which controls the loop so that the loop runs n times. For the iterative solution, we know in advance exactly how many times the loop would run. The recursive version uses the second definition: n! = n * (n - 1)!, which is naturally a recursive definition. It defines the factorial of n in terms of ...
