The rows of Pascal's triangle are conventionally enumerated starting with row = at the top (the 0th row). These row values can be calculated by the following methodology: For a given non-negative row index, the first row value will be the binomial coefficient where n is the row index value and k is 0). Write a function that takes an integer value n as input and prints first n lines of the Pascal’s triangle. But I believe many things influence a code. The question is from Leetcode site.

The first row is 0 1 0 whereas only 1 acquire a space in Pascal’s triangle, 0s are invisible. Given an index k, return the kth row of the Pascal's triangle. The 1st line = only 1's. Create a free website or blog at WordPress.com. However the problem asks for using only O(k) extra space. This post is regarding the "Kth row of Pascal's triangle" problem. So I want to know if it can be improved or not. Pascal’s triangle : To generate A[C] in row R, sum up A’[C] and A’[C-1] from previous row R - 1. The entries in each row are numbered from the left beginning with = and are usually staggered relative to the numbers in the adjacent rows.
