Rosalind Problem Solving in Python: Ep. 2 - Combinatorics

Join Phillip Compeau, Carnegie Mellon professor and Rosalind co-founder, for a Python live problem-solving session on Rosalind — a platform for learning bioinformatics through coding. In Episode 1, we tackle foundational problems. 00:00 Start screen 06:51 Stream starts: setup 13:20 FIB: Rabbits and Recurrence Relations 35:10 A recursive solution fails 47:32 PERM: Enumerating Gene Orders 1:01:58 LEXF: Enumerating k-mers Lexicographically 1:15:08 SIGN: Enumerating Oriented Gene Orderings 1:34:07: LEXV: Ordering Strings of Varying Length Lexicographically 1:53:45: FIBD (Final boss): Mortal Fibonacci Rabbits 2:30:31: Wrapping up, and happy coding!
