Answer 4

This is an version of your code without spelling mistakes.
As it looks like SoloLearn does nit Support

DataInputStream

SoliLearn does not even ask tye user for input...

Mybe you look at how SoloLearn wants you to search for user Input:

Answer 5

Type errors..
readLine() ; // not reqdline()
2*n, //not 2n
And as said already System.in..

1. The Input part

Thanks once again 🙏
