Write a program to get the electron configuration, given the atomic number. Assume that elements atomic numbers are between 1 to 118. Any programming language is fine but Java or Python is preferred.

class ElectronConfiguration

{    public static void main(String s[])
    {
        int atomicNumber = 20;
        String electronConfiguration = getElectronConfiguration(atomicNumber);
        System.out.println(electronConfiguration);

    }


public static String getElectronConfiguration(int atomicNumber) {
String result = null;
//Write code here to get the electronic configuration
return result;
}
}
