Chapter 5.9, Problem 36SC
Consider this slight modification of the printTriangle method:
public static void printTriangle(int sideLength)
{
if (sideLength < 1) { return; }
for (int i = 0; i < sideLength; i++)
{
System.out.print("[]");
}
System.out.println();
printTriangle(sideLength - 1);
}
What is the result of printTriangle(4)?
