LeetCode算法题-Pascal's Triangle(Java实现) 这是悦乐书的第170次更新,第172篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第29题(顺位题号是118)。给定非负整数numRows,生成Pascal三角形的第一个numRows。例如: 输入: 5 输出: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,...
result = next; }for(intin: result) { list.add(in); }returnlist; } 05 验证与测试 针对上面三种解法,选取部分随机数字并测试不同解法耗时,代码如下: publicstaticvoidmain(String[] args){ Easy_119_PascalTriangleII instance =newEasy_119_PascalTriangleII();introwIndex =3;longstart = System.nanoT...
welcome to my blog LeetCode Top Interview Questions 118. Pascal’s Triangle (Java版; Easy) 题目描述 Given a non-negative integer numRows, generate the first numRows of Pascal's triangle. 1. In Pascal's triangle, each number is the sum of the two numbers directly above it. Exampl...
既然讲到了Pascal‘s Triangle,即杨辉三角。那么就先去Wikipedia上面复习一下杨辉三角吧:”杨辉三角形,又称賈憲三角形、帕斯卡三角形、海亚姆三角形,是二项式係數在的一种写法,形似三角形。 杨辉三角形第n层(顶层称第0层,第1行,第n层即第n+1行,此处n为包含0在内的自然数)正好对应于二项式展开的系数。例如第二...
118. Pascal's Triangle Given a non-negative integer numRows, generate the first numRows of Pascal's triangle. Example: 当i=0,nums[0][0]=1 当i>0,numrow-1>j>0 , nums[i][j]=nums[i-1][j-1]+nums[i-1][...【LeetCode篇-Java实现】118. Pascal's Triangle 118. Pascal's ...

Pascal's Triangle 我用二项式解决了这个,其中溢出是用java的BigInteger解决的。但是看到大多数人是用定义解决的,计算量就不大,不会造成溢出leetcode:https://oj.leetcode.com/problems/pascals-triangle/Pascal's TriangleGivennumR... #39 s Triangle
