Pascal's Triangle leetcode java(杨辉三角) 题目: GivennumRows, generate the firstnumRowsof Pascal's triangle. For example, givennumRows= 5, Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 题解: 既然讲到了Pascal‘s Triangle,即杨辉三角。那么就先去Wikipedia上面复习...
Bonus point if you are able to do this using onlyO(n) extra space, wherenis the total number of rows in the triangle. 求出最小的路径。 第一次做使用递归,超时了。 publicclassSolution {publicintminimumTotal(List<List<Integer>> triangle) {intlen =triangle.size();intresult = triangle.get(...
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. Bottom-top DP class Solution { public int minimumTotal(List<List<Integer>> triangle) { int[] dp = new int[triangle.size()+1]; for (int i = triangle.size(...
GivennumRows, generate the firstnumRowsof Pascal's triangle. For example, givennumRows= 5, Return [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 解题思路: 观察法,JAVA实现如下: publicList<List<Integer>> generate(intnumRows) { List<List<Integer>> list =newArrayList<Lis...
2,3,4 (using the first 2) 2,3,4 (using the second 2) 2,2,3 Note: The length of the given array won't exceed 1000. The integers in the given array are in the range of [0, 1000]. Solution class Solution { public int triangleNumber(int[] nums) { ...
Return[1,3,3,1]. 解题思路: 每次在上一个list前面插入1,然后后面的每两个间相加赋值给前一个数。 代码描述: public class Solution { public List<Integer> getRow(int rowIndex) { List<Integer> result = new ArrayList<Integer>(); for(int i = 0; i <= rowIndex; i++){ ...
