# Project Euler Problem 67

Problem 67 is just a harder version of problem 18.

This is almost entirely cut-and-paste from problem 18, with the addition of a single function to load the triangle from a file:

(use '[clojure.contrib.duck-streams :only (read-lines)])

(time (euler-67 "/path/to/triangle.txt")) ;; "Elapsed time: 7.945236 msecs"
