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 have length()
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.
Graph adjacency list representation.
min(int a, int b, int c):

private static int min(int a, int b, int c) {
  int min = a;
  if (b < a) {
    min = b;
  }
  if (c < min) {
    min = c;
  }
  return min;
}
