As each row of Pascal's triangle has a unique length n, all we have to do is reconstruct the row, given its length, and check if it equals the original input. As each row is given by ( n − 1 i), 0 ≤ i < n, we just calculate that (as Jelly has a 1 byte for binomial coefficient)

Task. Given an index k, return the kth row of the Pascal’s triangle. For example, given k = 3, Return [1,3,3,1]. Note: Could you optimize your algorithm to use only O(k) extra space?
WebWe know that each number in this triangle is the sum of the two numbers directly above it. i.e. Num (row,col)= Num (row-1,col) + Num (row-1,col-1). So we can repeatedly call the function Num (rowIndex,j) for each column index of that row, and return the formed list. As we can see we have formulated recursive approach for finding Num (i,j).
