Q15: What is the output of the following loop?

for (int m = 0; m < 4; m++)
{
   for (int n = 5; n >= 0; n--)
   {
      System.out.print("#");
   }
   System.out.println();
}

Q16: What is the output of the following loop?

for (int m = 0; m < 4; m++)
{
   for (int n = 0; n <= m; n++)
   {
      System.out.print("$");
   }
   System.out.println();
}
