Answer:
Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. Greedy algorithms are used for optimization problems. An optimization problem can be solved using Greedy if the problem has the following property: At every step, we can make a choice that looks best at the moment, and we get the optimal solution of the complete problem.
If a Greedy Algorithm can solve a problem, then it generally becomes the best method to solve that problem as the Greedy algorithms are in general more efficient than other techniques like Dynamic Programming. But Greedy algorithms cannot always be applied. For example, the Fractional Knapsack problem (See this) can be solved using Greedy, but 0-1 Knapsack cannot be solved using Greedy.
The following are some standard algorithms that are Greedy algorithms.
1) Kruskal’s Minimum Spanning Tree (MST): In Kruskal’s algorithm, we create an MST by picking edges one by one. The Greedy Choice is to pick the smallest weight edge that doesn’t cause a cycle in the MST constructed so far.
2) Prim’s Minimum Spanning Tree: In Prim’s algorithm also, we create an MST by picking edges one by one. We maintain two sets: a set of the vertices already included in MST and the set of the vertices not yet included. The Greedy Choice is to pick the smallest weight edge that connects the two sets.
3) Dijkstra’s Shortest Path: Dijkstra’s algorithm is very similar to Prim’s algorithm. The shortest-path tree is built up, edge by edge. We maintain two sets: a set of the vertices already included in the tree and the set of the vertices not yet included. The Greedy Choice is to pick the edge that connects the two sets and is on the smallest weight path from source to the set that contains not yet included vertices.
4) Huffman Coding: Huffman Coding is a loss-less compression technique. It assigns variable-length bit codes to different characters. The Greedy Choice is to assign the least bit length code to the most frequent character. The greedy algorithms are sometimes also used to get an approximation for Hard optimization problems. For example, the Traveling Salesman Problem is an NP-Hard problem. A Greedy choice for this problem is to pick the nearest unvisited city from the current city at every step. These solutions don’t always produce the best optimal solution but can be used to get an approximately optimal solution.
Answer:
The correct answer is option (D) Identify the impact on safety of the property
Explanation:
Solution
In every Business Impact Analysis, the first and the most important step is for the CISO is to identify and estimate the impact of the aftereffects on the business and property of an organization that may be occurred from the disaster.
Physical security is very important, but it is not noticed by most organizations. It is important if you do not want anyone to take away your information or destroy it, in case of natural calamity. the reason could be that, the intruder is doing it for his personal achievement, financial gain,or seeking revenge or when one is taken unaware and becomes a target. If this security is not maintained properly all the safety measures will not be useful once the attacker gets through by gaining physical access.
Example of property can be software, equipment, facilities, company’s assets.
Answer:
The function in C++ is as follows:
int isSorted(int ar[], int n){
if (
|| 
){
return 1;}
if (![ar[n - 1]](https://tex.z-dn.net/?f=ar%5Bn%20-%201%5D)
< ![ar[n - 2]](https://tex.z-dn.net/?f=ar%5Bn%20-%202%5D)
){
return 0;}
return isSorted(ar, n - 1);}
Explanation:
This defines the function
int isSorted(int ar[], int n){
This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)
if ( || ){
return 1;}
This checks if the current element is less than the previous array element; If yes, the array is not sorted
if ( < ){
return 0;}
This calls the function, recursively
return isSorted(ar, n - 1);
}
The answer is C because they need to store a massive amout of data
for such experiment, you do it with care and to acquire and determine to put experience in it
Explanation:
because without you been or using experience the experiment will not correct
