title: Find the maximum sum travelling from the top of the triangle to the base. url: http://projecteuler.net/problem=18 desc: | By starting at the top of the triangle below and moving to adjacent numbers on the row below, the maximum total from top to bottom is 23. 3 7 4 2 4 6 8 5 9 3 That is, 3 + 7 + 4 + 9 = 23. Find the maximum total from top to bottom of the triangle below (See file input) solution: Instead of bruteforcing from top to bottom simply add the numbers from the bottom up and let the "highest" number win in a shootout solutions: solve.php: desc: Basic solution language: php solve.rb: desc: Basic solution language: ruby
