If the key is already present in the map, the old value is replaced. Returns  if the value was inserted,  if it was replaced.O(log n)|. Associate the given value with the given key. If the key is already present in the map, don't change the value. Returns  if the value was inserted,  otherwise.O(log n)T. Remove the given key and its associated value from the map, if present. Returns  if the value was deleted,  otherwise.O(log n)5. Return the value associated with the given key, or . O(n * log n)1. Construct a map from a list of key/value pairs.O(n)8.
