Given a positive integer N, return the Nth row of pascal's triangle.
Pascal's triangle is a triangular array of the binomial coefficients formed by summing up the elements of previous row.
Example :
1
1 1
1 2 1
1 3 3 1
For N = 3, return 3rd row i.e 1 2 1
Example 1:
Input:
N = 4
Output: 1 3 3 1
Explanation: 4th row of pascal's triangle
is 1 3 3 1.
Example 2:
Input:
N = 5
Output: 1 4 6 4 1
Explanation: 5th row of pascal's triangle
is 1 4 6 4 1.
Your Task:
Complete the function nthRowOfPascalTriangle() which takes n, as input parameters and returns an array representing the answer. The elements can be large so return it modulo 109 + 7. You don't to print answer or take inputs.
Expected Time Complexity: O(N) Expected Auxiliary Space: O(N)
