Prime factors of two consecutive numbers

If there is given two consecutive numbers n and (n+1) then if we define two sets s1 and s2 such that the member of s1 are prime factors of n and  the member of s2 are prime factors of (n+1).
So by the number theory the set s1 and s2 will be exclusive.
In set theory:
                 There will be no element which appear in both the sets.
eg.
    The two numbers are 24 and 25.
    s1={2,3}
    s2={5}

    The two numbers are 50 and 51
    s1={2,5}
    s2={3,17}

Easiest Method to Read and Write into Files Streams in Competitive Programming

                      T his article is about easiest way to perform read and write operation from file. File handling is one of the most important aspect of programming and it becomes more important when we do competitive programming. Here are some context when you need to deal with files in comptetive programming. 1) Some specific programming contests like Google Code Jam and Facebook Hacker Cup they provide a file for input. You have to read input from that file and write answers into a file and upload on server within limited time. 2) If you are trying to code for a problem. Suppose the problem was that a square matrix is given and you have to rotate the matrix by 90 degree clock-wise. First line of input indicate the total no. of test cases and first line before matrix represents size of matrix. Then input would be like this. 3 5 10 23 43 34 21 11 13 43 30 71 10 23 43 ...

WARN AEROSPIKE_ERR_CLIENT Socket write error: 111

If you are just typing aql on terminal and following error throwing while your aerospike server has been started successfully. WARN AEROSPIKE_ERR_CLIENT Socket write error: 111 It may happen because you had connected some other server before, Now you are trying to connect to your localhost or different server. To remove the above error just type full command: aql -h 127.0.0.1 -p 3000                           ( put server ip in case of other server rather than localhost) instead of jus aql.
