Large file sorter

Sorts large file lexicographically. Use program arguments to specify file and chunk size in kilobytes. E.g. "c:\temp\generated.txt" 20000

Algo:

1. Split file into chunks of specified size
2. Sort lines inside chunks
3. Use k-way merge to merge lines from chunks to result file

Large file generator

Use program arguments to specify lines count, max line length and file path. E.g. 100 100 "c:\temp\generated.txt"
