Given an integer rowIndex, return the rowIndexth (0-indexed) row of the Pascal's triangle.

\n\n

In Pascal's triangle, each number is the sum of the two numbers directly above it as shown:

\n\"\"\n

 

\n

Example 1:

\n
Input: rowIndex = 3\nOutput: [1,3,3,1]\n

Example 2:

\n
Input: rowIndex = 0\nOutput: [1]\n

Example 3:

\n
Input: rowIndex = 1\nOutput: [1,1]\n
\n
