Did you ever saw a char and thought: "Damn, 1 byte for a single char is pretty darn inefficient"? No? Well I did. So what I decided to do instead is to pack 5 chars, convert each char to a 2 digit integer and then concat those 5 2 digit ints together into one big unsigned int and boom, I saved 5 chars using only 4 instead of 5 bytes. The reason this works is, because one unsigned int is a ten digit long number and so I can save one char using 2 digits. In theory you could save 32 different chars using this technique (the first two digits of an unsigned int are 42 and if you dont want to account for a possible 0 in the beginning you end up with 32 chars). If you would decide to use all 10 digits you could save exactly 3 chars. Why should anyone do that? Idk. Is it way to much work to be useful? Yes. Was it funny? Yes.

Anyone whos interested in the code: Heres how I did it in C: https://pastebin.com/hDeHijX6

Yes I know, the code is probably bad, but I do not care. It was just a funny useless idea I had.

This is 100% true. I never plan on actually using this. It might be useful for working on microcontrollers like an ESP32, but apart from that the trade of for more computational power is not worth the memory savings.

Having seen many of Kaze's videos on N64 development, I've learned that the N64 has like 4x the processing power it needs compared to its memory. In hardware cases like that the trade-off of computational power and memory memory savings gets you some nice performance gains.
