question: returns all keys in the symbol table as an iterable . to iterate over all of the keys in the symbol table named st , use the foreach notation : for key key : st.keys . concode_field_sep TreeMap<Key,Value> st concode_field_sep Key ceiling concode_elem_sep boolean contains concode_elem_sep Iterator<Key> iterator concode_elem_sep Key min concode_elem_sep int size concode_elem_sep Key max concode_elem_sep Value get concode_elem_sep boolean isEmpty concode_elem_sep void main concode_elem_sep Key floor concode_elem_sep void delete concode_elem_sep void put
target: Iterable < Key > function ( ) { return st . keySet ( ) ; }
