Read position When a file is opened in this mode, data will be written at the end of the file's existing contents. append mode The expression NOT eof(myFile) is equivalent to eof(myFile) == False T/F when working with a sequential access file, you can jump directly to any piece of data in the file without reading the data that comes before it F T/F In most languages, when you open an output file and that file already exists on the disk, the contents of the existing file will be erased T T/F the process of opening a file is only necessary with input files. Output files are automatically opened when data is written to them F T/F The purpose of an EOF marker is to indicate where a field ends. Files typically contain several EOF markers F

COMPUTER SCIENCE Equal keys pose a problem for the implementation of binary search trees. a. What is the asymptotic performance of TREE-INSERT when used to insert n items with identical keys into an initially empty binary search tree? We propose to improve TREE-INSERT by testing before line 5 to determine whether z.key = x.key and by testing before line 11 to determine whether z.key = y.key.
