Overview
- Can this be turned into a graph problem? Can it be turned into a tree problem?
- Java API call to get a String of certain length made of spaces.
- Arrays have
.length, Strings havelength() - Lists have
size() - Map:
containsKey(T key)get(T key)Set<T> s = m.keySet()Collection<T> c = m.values()
- Digit character (‘0’ – ‘9’) to its int value (int)c – 48 (‘0’ is 48, ‘9’ is 57, ‘A’ is 65)
- LinkedList API (add(), iterate)
- List<Key>[] a; a = new List<Key>[10];
- The mathematics of a modulo of a negative number.
