double marks = Obj.nextInt();
if(marks<=0 || marks>=100)
{
System.out.println("error");
}
else if(marks<=25 && marks>=0)
{
System.out.println("F");
}
else if(marks>=26 && marks<=45)
{
System.out.println("E");
}
else if(marks>=46 && marks<=5)
{
System.out.println("D");
}
else if(51>=marks && 61>=marks)
{
System.out.println("C");
}
else if(marks>=61 && marks<=80)
{
System.out.println("D");
}
else if(81<=marks && 100>=marks)
{
System.out.println("A");
}
