linked-list | An alternative implementation of std collections | File Utils library

I am working in an environment where I cannot use heap memory but only stack memory. To not be constrained by the #[no_std] enviroment I tried to use stack memory as heap memory with the linked-list-allocator crate. This was my approach.

How can I call in batch a multiple level of array ?

I want to create an array of unique value with multiples data, then I will manage to make an associative array after unyfing the values.

I have a csv file with lot of value like this :

when I'm solving the problem Intersection of Two Linked Lists from Leetcode, I found that the HashSet solution doesn't work on my computer. The return result is always null, but it works well on Leetcode.

What does the --contains option do in git for-each-ref?

Does it only return a reference if its revlist has the commit specified after the --contains option on the command line? (e.g. Does git for-each-ref refs/heads --contains feature/test only return those heads that contain the commit feature/test in their revlist? (i.e. the list of commits between them and the first commit, namely git rev-list ))?

The Git docs (v. 2.31.1; see here) are actually outdated: the Notes section at the bottom states you can use the --merged and --no-merged options together, but this was made incompatible with this commit.

The definition provided in the docs is ambiguous: it reuses the word "contains" without clarifying what is meant by that. A reference is a name that points to only one SHA. The idea of "contains" suggests a reference refers to multiple commits, which only makes sense in the context of its git rev-list.

A commit can come after or before another (simply by time of commit), but if it is not reachable from that commit (i.e. if the commit is not merged into its branch), then the commit has no knowledge of it, so it can't be said to "contain" it.

This is why --merged and --no-merged together made sense: it would return the commits reachable from (at least one of) --merged and none of --no-merged.

What is meant by "contains"?..."has immediate parent X"? "has ancestor X"? "has cousin X"?

UPDATE:

It does seem I was using an older version of Git. Using both --merged and --no-merged together was incompatible in v2.28.1, but is now compatible in v2.31.1. Hence, the Git docs are not outdated.

It also seems this commit was made on Mar 21, 2017, so well before v2.31.1 (not sure which version exactly it was committed with).

Second, it does seem @LeGEC's answer makes sense (vis-a-vis --contains/--no-contains means "give me refs that have this commit after them" and --merged/--no-merged means "give me refs that have this commit before them".

Still, it would be nice if the Git documentation could be given further clarified. Using the word in the definition as they've done is very vague.

Because Git is a Directed Acyclic Graph (DAG), commits point to other commits in linked-list-fashion in one direction: backwards in time towards their ancestors. Hence, the names --merged/--no-merged and their description in terms of "reachability" make sense.

Does "contains" mean "after and reachable" (i.e. children), or simply "after" (i.e. commits made later in time)?

Since this is a plumbing command (which are used in custom scripts), I need to know exactly what it does and how it works so that my scripts won't have any unexpected side effects.

I'm supposed to write a function that scan input from user till enter and enter it to linked list. I cant scan it into a String and than put it in a list.

I wrote this code and doesn't enter the chars to linked list and doesn't exit from the console till I press Exit.

I get error ":( program is free of memory errors valgrind tests failed; see log for more information."

Here is my code:

I'm supposed to write a function called - "disAssemblyList" that gets a linked list of chars(without a dummy element). The function should move a nodes with big letters to "bigLetter" linked list (without a dummy element) , move nodes with small letters to "smallLetter" linked list, nums to "nums" linked list and other chars keep into original list.

I need to pass by reference the smallLetter, bigLetter and nums linked lists and return the list with other chars.

I need to scan the original list. The original list can be empty.

for example:

An original linked list:

I've got this question where I'm supposed to write a function called - "createList" that gets a linked list(without a dummy element) of ints. The function should remove every element that is bigger than the previous one and the next one. Also, I have to make a new linked list (without a dummy element) where I place all the removed elements from the original linked list. (The elements should stay in the same order that they appeared in the original linked list). (createlist is createListEx4() in my code)

For instance, an original linked list : 3->6->1->9->8->4->5;

would be updated to : 3->1->8->4;

The "removed elements" linked list would be: 6->9->5;

The function will return a pointer to the "removed elements" linked list

I wrote this code and I cant seem to understand how to make it work. There is a memory leak while I print the "removed elements" linked list, and doesn't return the correct elements.

I found the function below that reverses a linked list recursively:
