fgiga [73]4 years ago

The theory that your data is still recoverable by forensic analysis by well-financed governments, is based on a misunderstanding of a research paper from the mid 90s by Peter Gutmann, which looked at MFM floppy disks, not modern EPRML hard drives. Lifehacker describes the software that you will be using, Darik's Boot and Nuke, as "an open-source boot disk utility (read: works on nearly any computer) that supports a wide variety of disk wiping methods and operates from inside the computer's RAM, allowing it to scrub the disk thoroughly at a remove.

Consider a binary search tree where each tree node v has a field v.sum which stores the sum of all the keys in the subtree roote
AVprozaik [17]

Answer:

Each time you insert a new node, call the function to adjust the sum.

This method has to be called each time we insert new node to the tree since the sum at all the

parent nodes from the newly inserted node changes when we insert the node.

// toSumTree method will convert the tree into sum tree.

int toSumTree(struct node *node)

{

if(node == NULL)

return 0;

// Store the old value

int old_val = node->data;

// Recursively call for left and right subtrees and store the sum as new value of this node

node->data = toSumTree(node->left) + toSumTree(node->right);

// Return the sum of values of nodes in left and right subtrees and

// old_value of this node

return node->data + old_val;

}

This has the complexity of O(n).

. the fact that a web app is written to be run within any of the standard
Evgen [1.6K]

The correct answer is C) ease of use.

The fact that a web app is written to be run within any of the standard browser and on any platform on which that browser operates is called "ease of use."

The ease of use concept indicates that the product is "amicable" or "friendly" to use by most people because it is not required andy technical knowledge to operate the product. In this case,  the app is written to be run within any of the standard browser and on any platform on which that browser operates, so it is "friendly" to operate bu most systems. App's companies and software companies created this "ease of use" concept for many of their products so they can sell most of them because people know they are easy to use and functional.
