+ * Floyd's Triangle
+ * 
+ * Floyd's triangle is a right-angled triangular array of natural numbers, 
+ * used in computer science education. It is named after Robert Floyd. 
+ * It is defined by filling the rows of the triangle with consecutive numbers, 
+ * starting with a 1 in the top left corner:
+	1 
+	2 3 
+	4 5 6 
+	7 8 9 10
