Precomputation in algorithms refers to the act of running an initial computation ahead of run time to create a lookup table that may be used by an algorithm to avoid running the same computation repeatedly each time it is executed.
What is algorithm?An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially.
Algorithms are procedures for resolving issues or carrying out tasks. Algorithms include math equations and recipes.
Algorithms are used in programming. All online searching is done using algorithms, which power the internet.
The term "precomputation" in the context of algorithms refers to the act of performing an initial computation before the algorithm is actually used.
This creates a lookup table that the algorithm can utilise to avoid performing the same computation repeatedly each time it is used.
Thus, this way, precomputed tables are essential.

We have written a method called sum with an int[] parameter nums. We want our sum method to compute the sum of nums, but our code has a bug (or perhaps bugs?) in it.
Fix the bugs.
Answer:
Following are the code to this question:
public class Main//defining a class-main
{
public static int sum(int[] nums)//defining a method sum that accepts array
{
int total = 0;//defining integer variable total
for(int num : nums) // use for-each loop
{
total += num;//add array value in total variable
}
return total;//use return keyword to return the total value
}
public static void main(String []ar )//defining a main method
{
int[] nums={1,2,3,4,5};//defining 1-D array nums
System.out.println(sum(nums));//use print function to call sum method
}
}
Output:
15
Explanation:
In the class "Main", a static method, "sum" is defined, that accepts array in its parameter and inside the method, an integer variable "total" is define, that uses the for each loop to add array value in a total variable and use a return keyword to return its value.
Inside the main method, an integer array nums are defined, that holds store some values and use the print function to call the sum method.

(BRAINLIEST QUESTION) What are some challenges that will need to be overcome in order for the Internet of Vehicles to become a reality?
Answer:
Internet of Vehicles (IoV) is a concept in intelligent transportation systems (ITS) in which vehicles with IoV will be able to communicate with each other and [ublic networks through V2I (vehicle-to-infrastructure), V2P (vehicle-to-pedestrian) interaction, and V2V (vehicle-to-vehicle).
There are some challenges that will need to be overcome in order for the Internet of Vehicles to become a reality:
IoV is unable to predict human behavior and body language of other drivers so it can be dangerous sometimes to take respective actions that a normal vehicle driver can do. Risk of security challenges and security attacks is one of the biggest challenges as the networks can be manipulated.People have lack of trust in IoV due to privacy and health concern.The initial cost of IoV is very high that only few rich people can buy it.Multiple Choice

Which part of a network controls the flow of information among computers within a network?
•switch
•client
•server
•router
Answer:
Switch
Explanation:
A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device.
The part of a network that controls the flow of information among computers within a network is router. The correct option is D.
What is router?A router is a physical or virtual gadget that links two or more packet-switched computer networks.
A router examines a data packet's destination Internet Protocol address (IP address), calculates the best path for it to take, and then forwards it.
On computer networks, a router receives and sends data. Routers are frequently mixed up with network hubs, modems, and network switches.
Routers, on the other hand, can combine the functions of these components and connect with these devices to improve Internet access or assist in the creation of business networks.
A router, similar to a switch, routes data packets based on their IP addresses.
Thus, the correct option is D.
