In Coq, destruct more or less corresponds to a case analysis. It is similar to induction except that there's no induction hypothesis. Here is a (admittedly rather trivial) example of this tactic: Require Import Coq.Arith.Lt. Theorem atLeastZero : forall a, 0 <= a. Proof. intros. destr...

Using toDF By importing spark sql implicits, one can create a DataFrame from a local Seq, Array or RDD, as long as the contents are of a Product sub-type (tuples and ca...

Using named ranges allows you to describe the meaning of a cell(s) contents and use this defined name in place of an actual cell address. For example, formula =A5*B5 can be replaced with =Width*Height to make the formula much easier to read and understand. To define a new named range, select cell ...
