Answer:

if (x > 7 && Math.sqrt(x) < 3)

Explanation:

The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.

So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.

What are the overheads associated with recursive algorithms? [

Agata [3.3K]

Answer:

Lot of Stack place,Performance

Explanation:

recursive algorithm is an algorithm which calls itself till some condition satisfied.Recurssion takes a lot of stack space as each time a method calls itself.it effects the performance of the application if there are more number of function calls . Because each function call uses a lot of system resources for execution. So it will make your application to run slower

Since you are sitting in a coffee shop with your laptop computer and have connected to the internet through an unrestricted wi-fi connection,this type of wi-fi connection called hotspot.

<h3>What is the difference between hotspot and Wi-Fi?</h3>

WLAN is a wireless technology for local area networks (Local Area Networks). While the hotspot uses wifi to connect wireless devices to the internet. Without wifi, a hotspot does not exist. whereas wifi is used to generate a hotspot.

Because it uses your cell phone number to authenticate, a mobile hotspot is a secure network. You should be prompted to create a password on your phone, which you can later use on other devices to access the internet. As opposed to accessing free public Wi-Fi, a mobile hotspot is safer and more secure because of this.

Therefore, A hotspot is a physical site where users can connect to a wireless local area network (WLAN) with a router connected to an Internet service provider to access the Internet, generally using Wi-Fi.

scheduling is approximated by predicting the next CPU burst with an exponential average of the measured lengths of previous CPU

dexar [7]

SJF scheduling is approximated by predicting the next CPU burst with an exponential average of the measured lengths of previous CPU bursts.

<h3>What is SJF in operating system?</h3>

SJF is a term that connote Shortest Job First. It is said to be a type of CPU scheduling whose algorithm is linked with each as it is said to process the length of the next CPU burst.

Note that for one to be able to know the time for the next CPU burst to take place, one need to take the SJF into consideration as that is its function.

Hence, SJF scheduling is approximated by predicting the next CPU burst with an exponential average of the measured lengths of previous CPU bursts.

See options below

A) Multilevel queue

B) RR

C) FCFS

D) SJF
