-===== How PRNG works? ===== 
- 
-**Linear Congruential Generator** is most common and oldest algorithm for generating pseudo-randomized numbers. 
- 
-The generator is defined by the recurrence relation: 
- 
-<code> 
-Xn+1 = (aXn + c) mod c 
-</code> 
- 
-**NOTE:**  where 
- 
-  * **X** is the sequence of pseudo-random values. 
-  * **m**, 0< m- modulus. 
-  * **a**, 0< a <m- multiplier. 
-  * **c**, 0< = c<m- increment. 
-  * **x0**, 0<=x0<m- the seed or start value. 
- 
-The next random integer is generated using the previous random integer, the integer constants, and the integer modulus. 
- 
-  * To get started, the algorithm requires an initial Seed, which must be provided by some means. 
-  * The appearance of randomness is provided by performing modulo arithmetic.
