Problem
Given an index k, return the kth row of the Pascal's triangle.
Example
when k = 3, the row is [1,3,3,1].
JavaScript Code
function getRow(rowIndex) { var result = []; if (rowIndex < 0) return result; result.push(1); for (var i = 1; i <= rowIndex; i++) { for (var j = result.length - 2; j >= 0; j--) { result[j + 1] = result[j] + result[j + 1]; } result.push(1); } return result; } console.log(getRow(6));
