Maps become more difficult when we have a multilevel structure: mapping to/from structures. So, the methods we will implement are the constructors, the size method, the isEmpty method, the get method, and the toString method. They are highly recommended, but are not strictly required, and you will not be penalized for failing to follow these procedures.

Various relevant methods: setting, getting, obtaining the size, removing, adding, clearing, contains-checking. Some problems lend themselves better to recursion. Does the object that a variable refer to fill the given role? Linked Lists have sequential access. The ArrayList can be thought of as growing and shrinking, but its not actually growing and shrinking inside. Four different final exam questions on binary trees. You do not need to utilize all of them. Remember whats going on with the variable (declared type) vs the object (actual type). In addition, changes to address one area of feedback may introduce new errors or concerns in other areas. Sometimes, requesting a regrade yields a poorer performance then before - the TAs may make mistakes in or against your favor. All assessments will be submitted and graded via Ed.

Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. class should have the following public methods: Returns the number of times the given letter appears in, uppercase (your method shouldnt care). size += value - inventory[Character.toLowerCase(letter) - 'a']; inventory[Character.toLowerCase(letter) - 'a'] = value; // Retruns the current number of elements in the inventory, // Returns true if the count status is zero or empty, // Returns sorted display of innventory with lowercase letters, // sorted alphabetically and surrounded by square brackets, // Adds a given inventory to the standing inventory and, // Returns the combined sum of each alphabetical character, // LetterInventory other - the second data that will be added to the first data inventory, public LetterInventory add(LetterInventory other) {.
