+    Right Pascal Triangle pattern in java
+    Approach:
+        1) Identify the numbers of rows for the outer for loop
+        2) Identify the relation of column with respect to row.
+            In this case col = size-row+1
+        3) for each loop , print the respective element.
+
+    TIME COMPLEXITY: O(N^2)
+    SPACE COMPLEXITY: O(1)
+     Eg: For size = 5,
+        OUTPUT:
+                * 
+                * * 
+                * * * 
+                * * * * 
+                * * * 
+                * * 
+                *
