Answer:

Below is the required JAVA Code:

Explanation:

public static int largestDigit(int n) {

if (n < 0) {

return largestDigit(-1 * n);

} else if (n == 0) {

return 0;

} else {

int digit = n % 10;

int maxDigit = largestDigit(n / 10);

if (digit > maxDigit)

maxDigit = digit;

return maxDigit;

}

public class LargestDigitRecursive {

public static int largestDigit(int n) {

if (n < 0) {

return largestDigit(-1 * n);

} else if (n == 0) {

return 0;

} else {

int digit = n % 10;

int maxDigit = largestDigit(n / 10);

if (digit > maxDigit)

maxDigit = digit;

return maxDigit;

}

public static void main(String[] args) {

System.out.println(largestDigit(14263203));

System.out.println(largestDigit(845));

System.out.println(largestDigit(52649));

System.out.println(largestDigit(3));

System.out.println(largestDigit(0));

System.out.println(largestDigit(-573026));

System.out.println(largestDigit(-2));

}

_______________ are distinguished from microcontrollers by their complexity and increased on-chip resources.A. Systems on a chip

weeeeeb [17]

Answer:

the correct option is (A)

Explanation:

According to the given scenario, the system on a chip is a chip that is different from the microcontrollers in terms of complexity and rise on the chip resources

The system on a chip is a circuit i.e. integrated most the computer things

hence, the correct option is (A).

Therefore the rest of the options are wrong

2560x1600 (apple)vs 1920x1200 (Dell), is there a big difference between those 2 based on screen resolution ?

Solnce55 [7]

Answer:

Yes

Explanation:

1920x1200 is a non-standard resolution which may not be fully supported, usually 1920x1080 (1080p) is preferred and has been standardised as a display resolution.

2560x1600 (WQXGA) is a more standardised display resolution, and will offer a lot sharper and crisper images as more pixels are being used to render the image. As a rule of thumb, the higher resolution - the better.

The difference between these two resolutions is about the same difference as 1080p and 2k, you are going to get twice as crisp an image.

However there are other factors, such as refresh rate that may come into play with a comparison with these two.

Write a program that allows the user to enter the last names of five candidates in a local election and the number of votes rece

amm1812

Answer:

a= input("Enter the last name of first candidate: ")

aVotes= int(input("Enter Number of votes cast for "+ a + ": "))

b= input("Enter the last name of second candidate: ")

bVotes= int(input("Enter Number of votes cast for "+ b + ": "))

c= input("Enter the last name of third candidate: ")

cVotes= int(input("Enter Number of votes cast for "+ c + ": "))

d= input("Enter the last name of fourth candidate: ")

dVotes = int(input("Enter Number of votes cast for "+ d + ": "))

e= input("Enter the last name of fifth candidate: ")

eVotes = int(input("Enter Number of votes cast for "+ e + ": "))

votes= [aVotes,bVotes,cVotes,dVotes,eVotes]

aPercent= (round((aVotes/sum(votes))*100, 2))

bPercent= (round((bVotes/sum(votes))*100, 2))

cPercent= (round((cVotes/sum(votes))*100, 2))

dPercent= (round((dVotes/sum(votes))*100, 2))

ePercent= (round((eVotes/sum(votes))*100, 2))

print( a, ":", aVotes,"Votes", aPercent,"%")

print( b, ":", bVotes,"Votes", bPercent,"%")

print( c, ":", cVotes,"Votes", cPercent,"%")

print( d, ":", dVotes,"Votes", dPercent,"%")

print( e, ":", eVotes,"Votes", ePercent,"%")

winner= max(votes)

if winner==aVotes:

print(a," is the Winner")

elif winner==bVotes:

print(b," is the Winner")

elif winner==cVotes:

print(c," is the Winner")

elif winner==dVotes:

print(d," is the Winner")

elif winner==eVotes:

print(e," is the Winner")

else:

None

Explanation:

First section

a= input("Enter the last name of first candidate: ")

aVotes= int(input("Enter Number of votes cast for "+ a + ": "))

b= input("Enter the last name of second candidate: ")

bVotes= int(input("Enter Number of votes cast for "+ b + ": "))

c= input("Enter the last name of third candidate: ")

cVotes= int(input("Enter Number of votes cast for "+ c + ": "))

d= input("Enter the last name of fourth candidate: ")

dVotes = int(input("Enter Number of votes cast for "+ d + ": "))

e= input("Enter the last name of fifth candidate: ")

eVotes = int(input("Enter Number of votes cast for "+ e + ": "))

Collects the last name and the number of votes cast

Second section

votes= [aVotes,bVotes,cVotes,dVotes,eVotes]

places all the votes in a list.

The reason for this is to allow us use the "sum function" and "max function", to get the sum of all the votes.

Third section

aPercent= (round((aVotes/sum(votes))*100, 2))

bPercent= (round((bVotes/sum(votes))*100, 2))

cPercent= (round((cVotes/sum(votes))*100, 2))

dPercent= (round((dVotes/sum(votes))*100, 2))

ePercent= (round((eVotes/sum(votes))*100, 2))

calculates the percentage of all the votes cast for the individual candidates

Fourth section

print( a, ":", aVotes,"Votes", aPercent,"%")

print( b, ":", bVotes,"Votes", bPercent,"%")

print( c, ":", cVotes,"Votes", cPercent,"%")

print( d, ":", dVotes,"Votes", dPercent,"%")

print( e, ":", eVotes,"Votes", ePercent,"%")

prints out the candidates name, number of votes received and the percentage

Fifth section

winner= max(votes)

gets the maximum votes cast

Sixth Section

if winner==aVotes:

print(a," is the Winner")

elif winner==bVotes:

print(b," is the Winner")

elif winner==cVotes:

print(c," is the Winner")

elif winner==dVotes:

print(d," is the Winner")

elif winner==eVotes:

print(e," is the Winner")

else:

None

uses if statements to compare the maximum votes with the votes gotten by all the candidates to get a winner
