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...
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. Example: Input: 5 Output: [ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ] 1. 2. 3. 4...
