a. double x = -1 + 2 * r;
b. double x = -1 + 3 * r;
c. double x = -1 + 4 * r;
d. double x = -1 + 5 * r;

Write c function that can replace all the positive elements to 0 and negative to 1 in undefined length one-dimensional array. test your program in the main program by defining one-dimensional array of 6 elements

Which of the following statements correctly identifies a problem with sanitization methods? a. methods are not available to remove data ensuring that unauthorized personnel cannot retrieve data.b. even fully incinerated media can offer extractable data.c. personnel can perform sanitization steps improperly.d. stored data is physically etched into the media.

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.
