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] ]分析:此题其实就是表现出帕斯卡三角的特征:它是一个三角形矩阵,其顶端是 1,视为(row0).第1行(row1)(1&1)两个1,这...

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 ...
Although Pascal was not the first to identify this pattern, he was likely the first to publish it in his work titled Treatise on the Arithmetical Triangle. Figure 1: A visual of Pascals triangle. It shows the first 9 rows, where the 1st row is labeled as 0....
So Pascal's Triangle could also be an "n choose k" triangle like this one.(Note that the top row is row zero and also the leftmost column is zero)Example: Row 4, term 2 in Pascal's Triangle is "6" ... ... let's see if the formula works: (42) = 4!2!(4−2)! = 4!
