Write a program, with comments, to do the following: + a. ask the user to enter a positive integer (digits only) n. b. check the value entered to see if it corresponds to a positive integer. c. if the user entered a positive integer do the following: if 0 80 calculate 1.2 (0.2*n) then print n and the calculated result with a suitable message. 19 d. otherwise, print the message you did not enter a valid input!

Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". any value that is the same as the immediately preceding value is considered a consecutive duplicate. in this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. note that the last 3 is not a consecutive duplicate because it was preceded by a 7. write some code that uses a loop to read such a sequence of non-negative integers , terminated by a negative number. when the code finishes executing, the number of consecutive duplicates encountered is printed. in this case, 3 would be printed. assume the availability of a variable, stdin, that references a scanner object associated with standard input. that is, stdin = new scanner(system.in); is given.
