POP2 - play with prime numbers (II)
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
We define here a new prime number called prime of primes number (POP) is a prime number that consists of other prime numbers less than this number.
Example: 1013 consists of 101 and 3 and both are prime.
Notes: 2003 is not POP because leading zeros are not allowed.
The POP numbers must contain more than or equal two primes, and overlapping is not allowed .
The first line contains an integer T specifying the number of test cases. (T <= 200)
Followed by T lines, each line contains an integer m number 0 <= m <= 1018.
For each test case print single line contain the first integer greater than or equal to m and is (POP) .
3 10 100 1000
23 113 1013
