Largest. Write an algorithm that read 5 distinct integers and displays the largest value. Assume the input values are distinct integers. ISBN. The International Standard Book Number (ISBN) is a 10-digit code that uniquely specifies a book. The rightmost digit is a checksum digit that can be uniquely determined from the other 9 digits in the following manner: Multiply the first digit by 10, the second by 9, the third by 8, and so on, down to the ninth digit by 2. Add the values together. Divide the sum by 11. What is the remainder

Largest Number Algorithm

Input n1, n2, n3, b4, n5

if n1>=n2 and n1>=n3 and n1>=n4 and n1>=n5

Print n1 + "is the largest"

else if n2>=n1 and n2>=n3 and n2>=n4 and n2>=n5

Print n2 + "is the largest"

else n3>=n1 and n3>=n2 and n3>=n4 and n3>=n5

Print n3 + "is the largest"

else n4>=n1 and n4>=n2 and n4>=n3 and n4>=n5

Print n4 + "is the largest"

else

Print n5 + "is the largest"

End if

End

The remainder of a valid ISBN number is 0

ISBN Algorithm

input isbnnum

Length = Length (isbnnum)

if Length! = 10 then

return false;

end if

Checksum = 0

kounter = 0

do

Num = isbnnum[kounter] - '0'

if 0 > Num or 9 < Num then

return false

end if

Checksum = Checksum + (Num * (10 - kounter))

kounter = kounter + 1

while (kounter < 9)

lastnum = isbnnum[9]

if lastnum! = 'X' and (lastnum '9') then

return false;

end if

if lastnum = = 'X' then

Checksum = Checksum + 10

else

Checksum = Checksum + (lastnum - '0')

end if

if Checksum % 11 = = 0 then

Print "Checksum is "

Print Checksum

Print "Remainder is"

Print Checksum % 11

Step-by-step explanation:

The first algorithm determines the largest of 5 numbers

It first accepts input for 5 numbers named n1 to n5

Then it checks one after the other, the largest of the 5 numbers

The second algorithm determines an ISBN Number

1 : This line takes input for ISBN number in variable isbnnum

2 : This line computes the length of variable isbnnum

3: This line checks if the length of the isbnnum is equal to 10

4: If the length is not equal to 10, the algorithm stops execution

6,7: These lines initialise the variable checksum and kounter to 0

8 to 15: These lines compute the checksum using an iterative do loop statement

16: This line saves the last character of variable isbnnum to variable lastnu

17,18,19: These lines checks is lastnum is not X and it is not a number, the algorithm is stops execution of true

20 to 24: These lines add or remove the last character from the checksum

25 to 27: These lines check if the checksum can be divided by 11. If yes, the checksum is printed

28,29: These lines print the remainder, which is 0.
