Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below.

For example, given the following triangle

[
     [2],
    [3,4],
   [6,5,7],
  [4,1,8,3]
]

The minimum path sum from top to bottom is 11 (i.e., 2 + 3 + 5 + 1 = 11).

Note: Bonus point if you are able to do this using only O(n) extra space, where n is the total number of rows in the triangle.

You are to find a dynamic programming solution to this problem, and implement it on Leetcode.

Hints:

Turn in:

  1. Source code for your solution
  2. Samples runs showing the operation with input and outputs.
  3. An explanation of how this problem includes the concept of an optimal substructure.
  4. A complete runtime asymptotic analysis.

Be prepared to discuss you solutions in class.
