For example… We have discussed similar problem where we have to return all the rows from row index 0 to given row index of pascal’s triangle here – Pascal Triangle Leetcode 118. In this problem, only one row is required to return. For example, when k = 3, the row is [1,3,3,1]. Example: In Pascal's triangle, each number is the sum of the two numbers directly above it. leetcode分类总结; Introduction 1. 求和问题2sum, 3sum, k sum... 1.1. This can be solved in according to the formula to generate the kth element in nth row of Pascal's Triangle: r(k) = r(k-1) * (n+1-k)/k, where r(k) is the kth element of nth row. Note that the row index starts from 0. Note that k starts from 0. Merge Two Sorted Lists 27.
