Pseudorandom numbers are generated using a recurrence relation
$$R_i=(A×R_{i−1 }+B) mod C$$
Values of A=5,B=17,C=23,$ R_0$=3.
What will be the value of $R_{2018}$
or $R_n$ for that matter?

Writing a JSON file to server through Javascript
I wrote a chrome extension using javascript, which receives user inputs and using AJAX connect to PHP residing in the server to write them to specified folder in server.
I want to remove this PHP(server side) layer.
Is there any way I can directly write a JSON file to server, without the need of any server side language?
This will make my chrome extension portable across any web stack
Thanks in... -

Open Source Database required for storing huge data from Web crawler
I have an idea to implement a web application.

How many space is allocated by new int[z]?
I wrote following code.
int *p = new int[z];
cout<<sizeof(p)//comes out 4. OK

In my opinion p is pointing to address storing an array of z int element. It should be 4*z.
Can anyone please help?
