The random number generator produces the same sequence

https://github.com/DenCoder618/SUAI-Labs/blob/bc6708624c0c01c4fc916b406fcd50f1d92cfa9b/Lab_3/Lab_3.c#L41

sort_list function is not working properly

For example input file:

lorem ipsum dolor sit amet

Prints output:

amet sit dolor ipsum lorem

Why the 2nd word is sit ?? 🤔idk
Maybe this line has an error:

https://github.com/DenCoder618/SUAI-Labs/blob/8205dad7fef41f9d0cca3b3e29df00d199a40cae/Semester_1/Lab_6/Lab_6_new.c#L12

https://github.com/DenCoder618/SUAI-Labs/blob/55ffa5a86e2616c005ae8849003b7b6a486a25af/Semester_1/Lab_6/snippets.c#L316-L318

When removing duplicates on medium file, come words is corrupted (35 & 42):

34 -- libero
35 -- ╚"q
36 -- luctus
/ -------- /
41 -- mi
42 -- `)q
43 -- mollis

Idk what is this 👀

Rewrite this strcmp function!

https://github.com/DenCoder618/SUAI-Labs/blob/f656f77762e88ab3576a459b1851fc74185c5247/Lab_4/Lab_4.c#L38

And do not use fgets!

https://github.com/DenCoder618/SUAI-Labs/blob/f656f77762e88ab3576a459b1851fc74185c5247/Lab_4/Lab_4.c#L18

Last word in any line always ignored by program

For example:
arc arc ser arc ser ter ser arc
Gives the output:
arc - 3 times, ser - 3 times
which is wrong

But input:
arc arc ser arc ser ter ser arc gth
Gives the correct answer:
arc - 4 times, ser - 3 times

I think this is because of this line of code:
https://github.com/DenCoder618/SUAI-Labs/blob/6e2a3b3e248fec670a88efdb44b9a8f25378081c/Lab_2/Lab_2.c#L30 which did not expects \n symbol at the end of the line

implemented + and - operators for HugeInt class:

https://github.com/CyberPotat42/SUAI-Labs/blob/dde62c41c861727fae185773a0c00cd5660e65a9/Semester_2/Lab_12/HugeInt.cpp#L170

https://github.com/CyberPotat42/SUAI-Labs/blob/dde62c41c861727fae185773a0c00cd5660e65a9/Semester_2/Lab_12/HugeInt.cpp#L199

but they are not working properly:

618 + 42 = 660
618 - 42 = 6
-618 + 42 = 660
-618 - 42 = 6
618 + -42 = 660
618 - -42 = 6
-618 + -42 = 660
-618 - -42 = 6

When I try to multiply two polynomials like this:
https://github.com/CyberPotat42/SUAI-Labs/blob/619dbbbf28ac68fabacb6bf25052866939f0047d/Semester_2/Lab_9/main.cpp#L84-L95

This works great!

x - 1
x - 2
x^2 - 3x + 2

But when i try to multiply them in a loop:
https://github.com/CyberPotat42/SUAI-Labs/blob/619dbbbf28ac68fabacb6bf25052866939f0047d/Semester_2/Lab_9/main.cpp#L105-L118

Then for some reason the wrong answer is given:

input n = 2
input 2 numbers: 1 2

x - 1
x - 2
x^2 - 4x + 4

Perhaps this is due to incorrect handling of pointers or a memory leak
I think it's time for me to sleep 💤

Function removes elements with a shift, which leads to incorrect results

https://github.com/DenCoder618/SUAI-Labs/blob/2f2ddd9929bac01ea3d5520e2c60d0585ba725ae/Semester_1/Lab_6/snippets.c#L309

For example:

list: 0 1 2 3 4 5 6 7
remove_nodes from 5 to 8
expected output: 0 1 2 3 4
real output: <empty> [error]

Function that converts a character to lowercase does not work correctly

https://github.com/DenCoder618/SUAI-Labs/blob/b4f24c5ce8cedea0318080affee271b9a0aba78d/Semester_1/Lab_5/Lab_5_dop.c#L56

Example input:
HelloComMa WorldDoT How r UqStn

Expected output:
Hello, World. How r U?

But the program does not perform the replacement

I think this is because of Windows cp1251 encoding
