DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement.
Explanation:
- DHCP provides reliable IP address configuration, while reducing network administration.
- Discovery : The DHCP client broadcasts a DISCOVER message on the network subnet using the destination address or the specific subnet broadcast address. A DHCP client may also request its last known IP address
- Offer :When the server receives a DISCOVER message from a client, which is an IP address lease request, the DHCP server reserves an IP address for the client and makes a lease offer by sending a OFFER message to the client.
- Request : In response to the DHCP offer, the client replies with a REQUEST message, broadcast to the server,[a] requesting the offered address.
- Acknowledge : When the DHCP server receives the REQUEST message from the client, the configuration process enters its final phase. The acknowledgement phase involves sending a ACK packet to the client.
Answer:
import java.util.Scanner;
class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("How many numbers do you want to add?");
int numberOfNumbers = scanner.nextInt();
int arrayNumbers[] = new int[numberOfNumbers];
System.out.println("Enter " + numberOfNumbers + " numbers:\n");
for(int i = 0; i < numberOfNumbers; i++){
int addToArray = scanner.nextInt();
arrayNumbers[i] = addToArray;
}
int sum = 0;
for(int j = 0; j < arrayNumbers.length; j++){
sum+=arrayNumbers[j];
}
System.out.println("Sum: " + sum);
}
}

Explanation:
target_sum=float(input("Enter a target sum > 0 and <1 : ")) #asking user to enter the sum
while (target_sum<0 or target_sum>1): #if target sum not in range print the message
print("The target sum is not between 0 and 1")
target_sum=float(input("Please Enter a target sum > 0 and <1 : "))
computed_sum=0.00 #declare computed_sum
term_count=0 #declare term count and initalize to 0
r=1 #variable used to create the difference value
while computed_sum<target_sum: #iterate loop till computed sum is less than target sum
computed_sum=computed_sum+(1/(2**r)) #add previous computed sum with current term (1/2,1/4,1/8 etc)
term_count+=1 #increment term count
r+=1 #increment r value
print("Final Sum = " ,computed_sum) #finally print term count and final sum
print("Number of Terms= " ,term_count)
