在Pascal三角形中,每个数字是它正上方的两个数字的总和 Example Input:5Output:[[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]] C++输入格式 classSolution{public:vector<vector<int>>generate(intnumRows){}}; 范例一 classSolution{public:vector<vector<int>>generate(intnumRows){vector<vector...
给定一个整数 rowIndex ,返回杨辉三角的第 rowIndex 行。 在杨辉三角中,每一个数是它左上方和右上方的数之和。 进阶:使用空间复杂度为 O(n) 的方法。 数据限制 1 <= rowIndex <= 33 样例 思路:DP 本题是 LeetCode 118 这题的加强版,需要将空间复杂度优化为 O(n) 。
