Project Euler Problems 18 & 67

Problem #18 (Maximum Path Sum I):

Problem #67 Maximum Path Sum II):

The large triangles for both problems can be downloaded from the links I gave.

bobbym's Down the rows and columns game thread from 2012 has 3 more of these. I solved them longhand back then coz they were easy enough. Also, I just hadn't considered using code.

I solved #18 longhand, but #67 was much too big for that! I tried and failed with M & BASIC code, but worked out a nice Excel (spreadsheet) solution for each of them (including bobbym's). Had to google for a logic clue first, though.
