First see this example: let you have a number 8 which is divisible by 4 which is square of 2 and 27 which is divisible by 9 which is square of 3.I need a solution for numbers input from 1 to 10^18.hope for efficient program written in any programming language.
Thanks in advance.

My question is : it is very easy to find multiplication of two prime numbers but tough to get what are the prime numbers which multiplication results this number . Example : 7*11= 77 but you are given 77 = ? * ? where ?= two prime numbers only (ans = 7 and 11).Another example : 11*13= 143 but you need to solve it for 143 and you output : 11 13
So I need a program ,efficient one, to get solutions to such type of mathematical problem.
Adding more examples:
input:1. 21 -> 3,7
2. 189 -> 3,7,9
3.1363 -> 29,47 .... and if is not possible then print -1 example 1. 4 and its factors 2*2 where 2 is repeated so print -1
2. 9-> -1
3. 24->-1 ( prime factors are 2^3 * 3= 8*3 where 8 is not prime so print -1).
Thanks in advance.

Print all Jumping Numbers smaller than or equal to a given value.

A number is called as a Jumping Number if all adjacent digits in it differ by 1. The difference between ‘9’ and ‘0’ is not considered as 1.
All single digit numbers are considered as Jumping Numbers. For example 7, 8987 and 4343456 are Jumping numbers but 796 and 89098 are not.

Given a positive number x, print all Jumping Numbers smaller than or equal to x. The numbers can be printed in any order.

Example:

Input: x = 20
Output: 0 1 2 3 4 5 6 7 8 9 10 12

Input: x = 105
Output: 0 1 2 3 4 5 6 7 8 9 10 12
21 23 32 34 43 45 54 56 65
67 76 78 87 89 98 101

Note: Order of output doesn't matter,
i,e., numbers can be printed in any order

C++11 final classes

Are C++11 final classes really final, or is it still possible to define a derived class through some hack without violating language rules?

It seems we devirtualize calls to virtual members of final classes in some cases, so I assume final is really final, but I'm not sure. :-)
