+# Each new term in the Fibonacci sequence is generated by adding the
+# previous two terms. By starting with 1 and 2, the first 10 terms will be:
+#
+# 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...
+#
+# By considering the terms in the Fibonacci sequence whose values do
+# not exceed four million, find the sum of the even-valued terms.
