本文给出杨辉三角的几种C语言实现,并简要分析典型方法的复杂度。 本文假定读者具备二项式定理、排列组合、求和等方面的数学知识。 一 基本概念 杨辉三角,又称贾宪三角、帕斯卡三角,是二项式系数在三角形中的一种几何排列。此处引用维基百科上的一张动态图以直观说明(原文链接http://zh.wikipedia.org/wiki/杨辉三角):...
By using two-dimensional array, write C program to display a table that represents a Pascal triangle of any size. In Pascal triangle, the first and the second rows are set to 1. Each element of the triangle (from the third row downward) is the sum of the element directly above it and...

(Of course then you would have to center number of n - 2 digits or less to make it look like a triangle.) Dec 2, 2011 at 7:08pm Gaminic(1621) Addcout <<"Tilt your head 45° to the left."<< endl;at the end. Dec 2, 2011 at 7:15pm ...
Pascal’s Triangle is the triangular arrangement of numbers which gives the coefficients in the expansion of any binomial expression. Visit BYJU'S to learn Pascal's triangle formula, properties and many solved examples.
