蒙特卡罗通常在解决数学和物理方面的问题非常有用，典型的处理方法包含在文件中-Monte Carlo Method is often useful for solving problems in physics and mathematics where analytical methods are tough to apply. These methods use random numbers and uses the theory of probability to solve the problem. This method can be understood by solving small problems. This code demonstrates such an simple problem　calculation of pi using Monte Carlo Method.
