Both of these algorithms are used in some applications against collisions. The LISCH means late insertion standard coalesced hashing that have an insertion at the end. Instead the LISCH, the EISCH have an insertion at the beginning (early insertion).

Use GCC to compile. Using bash, just run a simple command::

$ gcc main.c -o output

First, you need to run the output file from gcc compiler.

$ ./output

After that, you will choose l to use LISCH algorithm or choose e to use EISCH algorithm.

The binaries files are saved on files folder with the correspondent algorithm name + .dat extension.
