Problem 4 The recursive function rotateDigits moves the first digit to the end of a positive integer. All other digits move one place to the left. For example rotateD1gits(12345) returns 23451. An implementation of this function with parts of the code covered up is given below. There is also a main program that uses it. Some pieces of code have been replaced by PART (a), PART (b), and so on. To answer the 5 parts of this question you should supply the C++ code that was replaced. Each answer must fit on a single line. 80

Question
Problem 4
The recursive function rotateDigits moves the first digit to the end of a positive integer. All
other digits move one place to the left. For example rotateDigits(12345) returns 23451.
An implementation of this function with parts of the code covered up is given below. There is also a main program
that uses it.
Some pieces of code have been replaced by PART (a), PART (b), and so on. To answer the 5 parts of this question
you should supply the C++ code that was replaced. Each answer must fit on a single line.
int rotateDigits (int x) {
if (x < 10) PART (a);
int y = PART (b);
х - PART (с);
int z = PART (d);
return PART (e);
int main() {
cout « rotateDigits (19683) « endl; // prints 96831
cout « rotateDigits (1024) <« endl;
cout « rotateDigits (19) <« endl;
cout « rotateDigits (9) <« endl;
// prints 241 because the o disappears
// prints 91
// prints 9
return 0;
