Write a sorting program by merging multiple files. Input files contain data of one of two types: integers or strings. The data is written in a column (each line of the file is a new element). Strings can contain any non-whitespace characters, strings with spaces are considered erroneous. It is also assumed that the files are pre -sorted.
