Nth row of pascal's triangle
Did you know?
WebPascal’s triangle is a triangular array of the numbers which satisfy the property that each element is equal to the sum of the two elements above. The rows are enumerated from the top such that the first row is numbered 𝑛 = 0. Similarly, the elements of each row are enumerated from 𝑘 = 0 up to 𝑛. WebEach row is dependent on the previous row, so you probably need to generate every row up till the nth row. The second row is not dependent on the first row — it’s simply [1,1] Challenge — try to do this recursively *** The 1) iterative solution, 2) recursive solution, and 3) One-liner solution are all included below ***
