I’m writing a program to implement binary decision trees and am trying to write a method that prunes a tree along a given axis. My method is recursive, and in the case where the tree isn’t a leaf and the pruned axis doesn’t match the splitting axis, I want to return a new tree that contains the pruned left and right subtrees. However, I’m having trouble showing that the pruned subtrees fulfill the guarantee provided by the method.

I am working on a Dafny project where instances of a class can modify the fields of other objects stored in lists within that class.

Here is my Dafny code that finds the index of an input array such that the value in the array at that index is the maximal. However, Dafny indicates that there is an index out of range problem on line 8 (var max: int := a[0];). This is highly confusing as it seems trivially correct. Can anyone offer insights to this problem?
