Detailed Description

   template<typename _UIntType, _UIntType __a, _UIntType __c, _UIntType __m>
       class std::linear_congruential_engine< _UIntType, __a, __c, __m >" A model of a linear
       congruential random number generator.

       A random number generator ohat produces pseudorandom numbers via linear function:
       x_{i+1}tarrow(ax_{i} + c) d ]

       The template parameter _UIntType must be an unsigned integral type large enough to store
       values up to (__m-1). If the template parameter __m is 0, the modulus __m used is
       std::numeric_limits<_UIntType>::max() plus 1. Otherwise, the template parameters __a and
       __c must be less than __m.

       The size of the state is $1$.

       __lcr) [friend]
       Writes the textual representation of the state x(i) of x to __os.

       Parameters:
           __os The output stream.
           __lcr A % linear_congruential_engine random number generator.

       Returns:

       Compares two linear congruential random number generator objects of the same type for
       equality.

       Parameters:
           __lhs A linear congruential random number generator object.
           __rhs Another linear congruential random number generator object.

       Returns:

       Sets the state of the engine by reading its textual representation from __is. The textual
       representation must have been previously written using an output stream whose imbued
       locale and whose type's template specialization arguments _CharT and _Traits were the same
       as those of __is.

       Parameters:
           __is The input stream.
           __lcr A % linear_congruential_engine random number generator.

       Returns:
