[Question]
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).
[Solution]
//C++ class Solution { public: int minimumTotal(vector& triangle) { if(triangle.size()==0) return 0; if(triangle.size()==1) return(triangle[0][0]); for(int i=triangle.size()-2; i>=0; i--){ for(int j=0; j<=i; j++){ triangle[i][j] += min(triangle[i+1][j], triangle[i+1][j+1]); } } return triangle[0][0]; } };
