 <p>The first five rows of the Pascal's triangle look like this:</p>
 <pre>
-        1
-       1 1
-      1 2 1
-     1 3 3 1
-    1 4 6 4 1
+    1
+   1 1
+  1 2 1
+ 1 3 3 1
+1 4 6 4 1
 </pre>
 <p>
 Each row begins and ends with 1. Every other element can be obtained as a sum of the two values above it. Write the predicate <code>pascal(I,J,N)</code> that returns the <code>J</code>-th value in the <code>I</code>-th column of the Pascal's triangle. Your solution should return exactly one answer for any input (the <code>I</code> and <code>J</code> arguments start counting with 0; you can assume that 0 ≤ <code>J</code> ≤ <code>I</code>).

-  ?- pascal(2, 1, N).
-    N = 2.
-  ?- pascal(4, 3, N).
-    N = 4.
