can not compress large file

[8banzhuan]

hello，i just use it to compress a file that size of 3GB ，then i get ：
terminate called after throwing an instance of 'std::length_error'
what(): basic_string::_M_replace_aux
Aborted
I would appreciate it if you could give me some advice

Hi,
I've made this project for learning purposes, I wanted to learn more about compression algorithms and low-level bit operations in C++.

Currently, I'm loading the whole file in memory and apply multiple algorithms on it, unfortunately some of them use large amount of memory (specifically Suffix Array in BWT).
Therefore for large files you will face errors for being out of memory.

Memory optimization and splitting the file into chunks are on my TODO list, but unfortunately I don't have enough time to work on it.
I will try to fix that on my free time if I can.

Thanks

Hi, thank you for your timely reply and look forward to your good news. At present, I have just started to learn about data compression. Thank you for your project and I have learned a lot
