Answer 2

Online Mining junction ,
i have the feeling that the task description is not complete. let me ask you:
-> are the numbers that should be summed: 1 x 1digit, 1 x 2 digit, 1 x 3 digit, 1 x 4 digit ?
-> should the sequence of the digits in your sample be all in ascending order for each number ?
these are the prime numbers that can be build from 1234 with ascending order of the digits:
[2, 3, 11, 13, 23, 113, 223, 233, 1123, 1223, 2333] i can not see a clear rule how the numbers you mentioned are selected

Answer 3

Which language are you using? Can you add your attempt from the code playground here and explain what isn't working?
I don't think you're expecting someone to do your homework for you, right?

Answer 4

It's no bother and it's nice you're helping your brother. Make him write the code into the code playground and attach it here and someone can help him
