The operating systems, and utility programs that perform system

Phantasy [73]

Answer:

System softwares.

Explanation:

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Basically, softwares are categorized into two (2) main categories and these are;

I. Utility software.

II. System software.

The operating systems, and utility programs that perform system maintenance and protection tasks such as error correction and backup are called system softwares.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

On the other hand, a utility software can be defined as a software application or program designed to add more functionality to a computer system, as well as to improve its performance efficiently. Some examples of commonly used utility tools in computer are file and folder backup tools, file management, antivirus, hard disk diagnostics, registry cleaner, network performance monitor, screensavers etc.

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 Canterbury Tales, written towards the end of the fourteenth century by Geoffrey Chaucer, is considered an estates satire because it effectively criticizes, even to the point of parody, the main social classes of the time. These classes were referred to as the three estates, the church, the nobility, and the peasantry, which for a long time represented the majority of the population.
