The Triangle Time Limit : 2000/1000ms (Java/Other) Memory Limit : 20000/10000K (Java/Other) Total Submission The first line contains one integer N: the number of rows in the triangle. The following N lines describe the data of the triangle. The number of rows in the triangle is > 1 but <= 100. The numbers in the triangle, all integers, are between 0 and 99.
Given a triangle, find the minimum path sum from top to bottom. For example, given the following triangle The minimum path sum from top to bottom is 11 (i.e., 2 + 3 ) { int len = triangle.size(); dp[0][0] = triangle[0][0]; for(int i= { if(j==0) dp[i][j] = triangle[i][j]+dp[i-1][j]; dp[i][j] = min(triangle[i][j]+dp[i-1][j],triangle[i][j]+dp[i-1][j-1]); } }

Pascal’s Triangle Desicription Given numRows, generate the first numRows of Pascal’s triangle.
以i 为最大边,第二边为i-1、i-2、...2 的三角形分别有 i-2个、i-3、... 、1个,总共就有(i-1)*(i-2)/2个。有(i-1)/2条边算到了两边相等,也就是要减去 (i-1)/2,因为第二边的在第三边出现了,所以算了两次,再除以2。
Question: Given numRows, generate the first numRows of Pascal's triangle.
Given a triangle, find the minimum path sum from top to bottom. For example, given the following triangle [ [2], [3,4], [6,5,7], [4,1,8,3] ] The minimum if you are able to do this using only O(n) extra space, where n is the total number of rows in the triangle class Solution { public: int minimumTotal(vector<vector<int>>& triangle) { vector<vector< int>> dp=triangle; for(int i=1;i<dp.size();i++) { for(int j=0;j<dp[i].size
动态规划问题,题意是输入一个数字三角形,然后从上往下走一条路,问走到底端的最大值。如果从上往下走的话会有很多种情况,所以不如反过来从下往上递推,比较大小求最大值。
