    119 - Pascal’s Triangle II.

    Easy

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

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

    Example 1:

    Input: rowIndex = 3

    Output: [1,3,3,1]

    Example 2:

    Input: rowIndex = 0

    Output: [1]

    Example 3:

    Input: rowIndex = 1

    Output: [1,1]

    Constraints:

    • 0 <= rowIndex <= 33

    Follow up: Could you optimize your algorithm to use only O(rowIndex) extra space?
