An algorithm of deleting linked 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.
Algorithm for finding min element in a linked list?
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;}
Explain the different searching techniques in c?
In computer science, a search algorithm, broadly speaking, is an algorithm that takes a problem as input and returns a solution to the problem, usually after evaluating a number of possible solutions. Most of the algorithms studied by computer scientists that solve problems are kinds of search algorithms.[citation needed] The set of all possible solutions to a problem is called the search space. Brute-force search, otherwise known as naïve or uninformed, algorithms use the simplest method of the searching through the search space, whereas informed search algorithms use heuristic functions to apply knowledge about the structure of the search space to try to reduce the amount of time spent searching.
What are the 5 ways of writing an algorithm?
for the most part, programming is writing algorithms. An algorithm is just a sequence of instructions designed to get a desired result.lets write an algorithm for finding the largest number in a list of numbers:You have a list called numberList and it has a bunch of random numbers stored in it. The only way you can find the largest number is if you go through every element in numberList. Since we don't know anything about any of the numbers in numberList (they could all be the same) lets just call the first element in the list our currentLargest. As we traverse through numberList, if we come across a number larger than our currentLargest then we assign the new number as our currentLargest. Once we have looked at every element in the numberList, our currentLargest should be the largest number in numberList.The code for the above program would look something like this [Pseudocode]:numberList = {1, 39, 8, 109, ...}currentLarget = numberList0FOR every element in numberList. . . IF element > currentLargest. . . . . . currentLargest = elementPRINT currentLargest
How do you compare items in a linked list?
You compare items in a linked list by searching for them. Iterate through the list, comparing elements with the search key. If you encounter end-of-list, then the key is not found, otherwise you have found the element desired. Note that this is a half linear search. Statistically, if an element is to be found, it will be found at the halfway point, assuming uniformly random distribution of data. In the worst case, if the element is not found, it will always take a full search to prove that. You could keep the linked list in order, by inserting each element before the element that has higher key value. This would reduce search time to half, because searching would stop with the element with higher key value. Searching is not a very efficient use of a linked-list. It would be better to use some kind of ordered list, perhaps a dynamic array with binary search, or a balanced binary tree, which has similar search performance but one with the most cost to design and implement. Linked-lists are better for keeping elements in the order they were encountered or inserted, such as processing tokens in a compiler. Sorry, but every solution has its tradeoffs.

Why not use seconds to evaluate algorithm's effectiveness?
An algorithm cannot be measured in seconds because:* timing will be different on different machines * timing will be different on the same machine in a different configuration * when an algorithm takes n seconds to complete, that only holds true for one set of inputThe biggest problem up there is that timing an algorithm only gives us information about one output for a specific input. What we really want to know is how well the algorithm will scalewith input. If you double the number of values you send as input will your algorithm take twice as long? Four times? Will it not scale linearly?In computer science we use what is known as "Big O notation" to describe how well an algorithm scales. Let's look at some common examples:Linear search can be represented in Big O as O(n). This is because the algorithm searches through each element in your list one at a time until it finds the target value. For a list of any size n, it will make n comparisons.Selection sort can be represented as O(n2) for the same reason. For a list of size n, each element will need to be compared to each other element, giving us n*n comparisons.More complex algorithms have more difficult evaluations.A binary search algorithm will cut the amount of data it needs to search in half on each iteration. This gives us O(log n).

What are disadvantage of algorithm?
Advantages of an Algorithm: Effective Communication: Since the algorithm is written in English like language, it is simple to understand the step-by-step solutions of the problems. Easy Debugging: Well-designed algorithm makes debugging easy so that we can identify a logical error in the program. Easy and Efficient Coding: An algorithm acts as a blueprint of a program and helps during program development. Independent of Programming Language: An algorithm is independent of programming languages and can be easily coded using any high-level language. Disadvantages of an Algorithm: Developing algorithms for complex problems would be time-consuming and difficult to understand. Understanding complex logic through algorithms can be very difficult.

Improving security in real time wireless networks through packet scheduling?
In the present network we have not a security of your data so you can do develop a some algorithm,that is useful to protect the packets in dynamically,but now used algorithms can't protect the packets,so we can develop spss algorithm,this algorithm is more protect the packets compare to other algorithms.......
