Implementing Taylor Series in APL
A short explanation behind my implementation of the Taylor Series in APL.
Explanation of my Code Guessing entry (round 6)
An analysis of my code guessing round 6 entry.
Matrix Rearrangements - solving a problem with APL.
Given a NxM matrix, one can pick a single element from each row so that the cost of this operation is the smallest. The cost is defined as the sum of every other element left in a row. For each column containing nonzero elements, an element must be picked so that every other element besides the chosen one must originate from different rows. What is the lowest cost for a given matrix?
What does GCD have in common with leap years?
If [ gcd(80, x) > gcd(50, x) ], then year x is leap. But why?
