    A few easy examples of CPU-intensive tasks:

    • searching for prime numbers (involves lots of BigInteger divisions)
    • calculating large factorials e.g. 2000! ((involves lots of BigInteger multiplications)
    • many Math.tan() calculations (this is interesting because Math.tan is native, so you’re using two call stacks: one for Java calls, the other for C calls.)
