+
+> **ATTENTION :** Sur les PCs de l'IUT, vous devrez ajouter une exception
+> à la configuration du proxy d'IntelliJ. Dans les paramètres,
+> `Settings... > System settings > HTTP proxy`, ajoutez l'adresse suivante
+> dans le champ `No proxy for` = `nexus.dep-info.iut-nantes.univ-nantes.prive`
+
+
+## Préliminaires
+
+Vous pouvez exporter le code du TP précédent sous la forme d'une bibliothèque `.JAR` 
+à importer dans ce TP si vous l'avez terminé.
+
+Sinon, des `.JAR` sont déjà présents dans `libs/`.
+
+
+## implémentations itératives
+
+La classe `IterativeBinarySearchTree` hérite de `BinarySearchTree`.
+
+![manquante](specifications/IterativeBinarySearchTree.png)
+
+
+Proposez dans la classe `IterativeBinarySearchTree` une implémentation itérative de (certaines) des méthodes récursives de `BinaryTree` et `BinarySearchTree`.
+
+Traitez les méthodes dans l'ordre indiqué. 
+
+> NB : il sera souvent nécessaire d'utiliser une **file** OU une **pile** :
+>
+>        val queue: Queue<X> = LinkedList()
+>        queue.offer(x)
+>        queue.poll() --> X
+>        
+>        val stack: Deque<X> = LinkedList()
+>        stack.push(x)
+>        stack.pop()  --> X
+
+Des cas de tests spécifiques sont fournis.
+
+**Pour aller plus moin :** implémentez les méthodes manquantes de `BinarySearchTree` dans `IterativeBinarySearchTree`.

+#
+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
