Triangle 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 [ [], [,4], [6,,7], [4,,8,3] ] The minimum path sum from top to bottom is…

118 - Pascal's Triangle Given numRows, generate the first numRows of Pascal's triangle. For example, given numRows = 5,Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] Solution: class Solution { public: vector<vector<int>> generate(int n…

一.Pascal's Triangle Given numRows, generate the first numRows of Pascal's triangle. For example, given numRows = 5,Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] class Solution { public: vector<vector<int>> generate(int numRows) { vect…

Pascal's Triangle Given numRows, generate the first numRows of Pascal's triangle. For example, given numRows = 5,Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] class Solution: # @return a list of lists of integers def generate(self, numRows):…

题意:给一个数字,返回一个二维数组,包含一个三角形. 思路:n=0.1.2都是特例,特别处理.3行以上的的头尾都是1,其他都是依靠上一行的两个数.具体了解Pascal三角形原理. class Solution { public: vector<vector<int> > generate(int numRows) { vector<vector<int> > ans; if(!numRows) return ans; vector<int> tm…

118. Pascal's Triangle 第一种解法:比较麻烦 https://leetcode.com/problems/pascals-triangle/discuss/166279/cpp-beats-1002018.9.3(with-annotation) class Solution { public: vector<vector<int>> generate(int numRows) { vector<vector<int>> result;…

我是按难度往下刷的,第二道是帕斯卡三角形二.简单易懂,题目如下: Given an index k, return the kth row of the Pascal's triangle. For example, given k = 3, Return [1,3,3,1]. Note: Could you optimize your algorithm to use only O(k) extra space? 就是输入k然后输出第k行帕斯卡三角[其实我一直把它叫杨辉三角]. 我这边思路是拿…

题目: Given an index k, return the kth row of the Pascal's triangle. For example, given k = 3,Return [1,3,3,1]. Note:Could you optimize your algorithm to use only O(k) extra space? 代码:oj测试通过 Runtime: 48 ms class Solution: # @return a list of integers d…

1.题目描述 Given numRows, generate the first numRows of Pascal's triangle.   For example, given numRows = 5, Return   [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ]   2.解法分析 这个题目很简单,所以不需要额外的解说,一遍就AC了 class Solution { public: vector<vector<int> >…
