Uses the combinatorics property of the Triangle: For any NUMBER in position INDEX at row ROW: NUMBER = C(ROW, INDEX) A hash map stores the values of the combinatorics already calculated, so the recursive function speeds up a little. Pascal’s triangle is an array of binomial coefficients. 4. Benjamin Schmitt. From the wikipedia page the kata author cites: "The rows of Pascal's triangle (sequence A007318 in OEIS) are conventionally enumerated starting with row n = 0 at the top (the 0th row)." To build a Pascal Triangle we start with a "1" at the top. Algorithm. pascals_triangle=lambda n:[[i for i in str(11**j)] for j in range(n)] Mh 9 years, 10 months ago # | flag for sure it works just for ´n<6´ since it would cut the ´10´ to ´1, 0´ etc. AskPython is part of JournalDev IT Services Private Limited, K-Nearest Neighbors from Scratch with Python, K-Means Clustering From Scratch in Python [Algorithm Explained], Logistic Regression From Scratch in Python [Algorithm Explained], Creating a TF-IDF Model from Scratch in Python, Creating Bag of Words Model from Scratch in python.
