Problem 1885. Minimum Sum thru a Lower Triangle
This Challenge is to find the minimum cumulative sum that traverses from row-1 thru row-N via vertical/diagonal adjacent elements of adjacent rows.
The input is a series of values of length n*(n+1)/2.
Input: S [Series that can be converted into a lower triangle]
Output: MinSum [Minimum cost path from top to bottom]
Example:
[5 7 6 3 2 5] becomes
5 0 0 7 6 0 3 2 5
Creates a MinSum of 13 [5+6+2]. The 5 can only see 6, 3 sees 7 and 6, while 2 sees 7 6 0.
