Question
![Consider the following Java class contained in Mystery.java, and compiled:
public class Mystery {
public static void main(String[] args) {
int current = = -1:
int count = O:
while (!Stdln.isEmpty()) {
}}}
int x = stdin.readlnt():
if (x != current) {
}
if (count > 0)
count++;
% more input1.txt
0 0 0 0 1 1 1 1
StdOut.print(count);
current = x;
count = 0;
A. Assume the contents of the file input.txt are given below (note: the line starting
with % is what you type on the command line prompt / the terminal; what
follows is the actual content of the file input1.txt).
Suppose that you execute the following command. What is
standard output? Write your answer in the space provided.
% java-introcs Mystery < input1.txt
B. Repeat the previous question, but with the following input file.
% more input2.txt
0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 0 0 0 1 1 1 0 1 1 1
% java-introcs Mystery < input2.txt
