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 is linear search algorithm?
The linear search problem relates to searching an un-ordered sequence. Because the data is no ordered, we must start at one end of the sequence and inspect each element in turn tunil we find the value we are looking for. If we reach the one-past-the-end of the sequence, the value does not exist. From this we can see that for a set of n elements, the worst case (the element does not exist) is O(n) time while the best case is O(1) time (the element we seek is the first element). Given that there is a 50/50 chance the element we seek will be closer to the start of the sequence than the end, the average seek time is O(n/2). When a set is ordered we can reduce search times by starting in the middle of the set. In this way, if the element is not found we can eliminate half of the set because we know which half contains the value (if it exists). We repeat the process until we find the value in the middle of the remaining set or the remaining set is empty. The end result is that search times are reduced to a worst case of O(log n), the binary logarithm of n.
How do you break up cement?
Brute, manual effort. A sledgehammer or jack hammer are the two most common methods for a cement slab or sidewalk. Roadways need much bigger equipment.

Number of unsuccessful logon attempts
What is the difference between breadth first search and best first search?
The main difference is that depth-first uses a stack while breadth-first uses a queue. To illustrate, imagine a binary tree where every node has up to two child nodes and some data. We begin at the root in both cases. With breadth-first, we enqueue the root. We then begin an iterative process. First, we dequeue a node. If the node contains the data being sought then we're done. Otherwise we enqueue the node's immediate children. If the queue is empty, the data being sought does not exist and we're done. Otherwise we begin a new iteration. With depth first we do the same thing except we stack the nodes (push and pop rather than enqueue and dequeue). Queues are a FIFO structure (first in, first out) while stacks are LIFO (last in, first out). This dramatically alters the sequence in which nodes are examined. Breadth-first examines nodes in sequence, row by row, whereas depth-first examines the depths of the left hand side of each node before examining the depths of the right hand side of each node. Depth-first is ideally suited to brute force backtracking algorithms (particularly NP-complete problems) as well as for rapidly building sorted lists from unsorted sequential data. Breadth-first search is better suited to creating diagrams from binary trees because a single pass can determine the number of levels and the maximum width required to display the tree, while a second pass can build the diagram one row at a time (typical breadth-first implementations will maintain the width and height as internal members to avoid recalculating them). Because depth-first employs a stack, implementations often make use of recursion rather than iteration, thus taking advantage of the call stack to provide the necessary backtracking. However, an iterative approach is usually more efficient, particularly if the tree depth exceeds the compiler's ability to inline expand the recursions.
Difference between informed search techniques and uniformed search techniques?
Informed search techniques use domain-specific knowledge to guide the search process, focusing on exploring promising areas first. Uninformed search techniques, on the other hand, have no information about the goal and rely on blind exploration of the search space. Informed search techniques are typically more efficient than uninformed search techniques in finding solutions to problems.
