Is a list (potentially) divisible by another? Question: Problem Say you have two lists A = [a_1, a_2, …, a_n] and B = [b_1, b_2, …, b_n] of integers. We say A is potentially-divisible by B if there is a permutation of B that makes a_i divisible by b_i for all i. The problem is …
Floor division with negative number Question: The expression 6 // 4 yields 1, where floor division produces the whole number after dividing a number. But with a negative number, why does -6 // 4 return -2? Asked By: Naz Islam || Source Answers: The // operator explicitly floors the result. Quoting the Binary arithmetic operations …
Is divmod() faster than using the % and // operators? Question: I remember from assembly that integer division instructions yield both the quotient and remainder. So, in python will the built-in divmod() function be better performance-wise than using the % and // operators (suppose of course one needs both the quotient and the remainder)? q, …
