In a linked list, there is no way to find the "min element" or any other element with a specific property except by walking through the entire list. Of course, you could store a pointer to the min element and update that each time the list changes (add ing or deleting an element), which makes the list less generic and a tiny bit slower but is worth it if you need this min element often.
Pseudocode for finding the min element (I'm assuming you're storing values and you want the element with the lowest value):
ptr_minelement = null;
ptr_element = ptr_firstelement;
while (ptr_element != null) {
if (ptr_minelement == null) or (ptr_minelement->value > ptr_element->value)
ptr_minelement = ptr_element;
ptr_element = ptr_element->ptr_next;
}
theory part to how u can insert element at middle of link list ?
To delete a linked list walk through the list and delete the memory allocated to each element, remembering the next element address, and then iterating or recursing the process using the next element address, until the next element address is null.
pseudo code algorithm to create a linked list
To search for an element in a linked list, you iterate the list, looking for the element, and either return the element or an indication that it was not found. for (ptr = first; ptr != null; ptr = ptr.next) if (ptr.value == searchvalue) break; This will either leave ptr with the address of the found element, or null, if not found.
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.

Linear time. O(n).
Insert newNode into a linked list after targetNode Node currentNode = root while currentNode != targetNode currentNode = currentNode.next newNode.next = currentNode.next currentNode.next = newNode
A list is an abstract data structure, usually defined as an ordered collection of data. A linked list refers to a specific implementation of a list in which each element in the list is connected (linked) to the next element.
Basically you split the list in two, looking at the element in the middle of the list. If the list is in ascending order, and the element you are looking for is SMALLER than the element in the middle of the list, you repeat this procedure for the FIRST half of the list (again, splitting it in two); if it is LARGER, you repeat for the SECOND half of the list.

In linked list, there are various operations in linked list that you can perform on linked list, eg: adding new elements, deleting elements, getting the first element, getting the next element after an element, any many others.
The pseudocode for the selection sort algorithm is as follows: Start with the first element as the minimum. Compare the minimum with the next element in the list. If the next element is smaller, update the minimum. Continue this process until the end of the list is reached. Swap the minimum element with the first element. Repeat the process for the remaining elements in the list. Selection sort works by repeatedly finding the minimum element from the unsorted part of the list and swapping it with the first unsorted element. This process continues until the entire list is sorted.
The time complexity to find an element in a linked list is O(n), where n is the number of elements in the list. This means that the time it takes to find an element in a linked list increases linearly with the number of elements in the list.
