Write a program ThueMorse. java that takes an integer command-line argument n and prints an n-by-n pattern like the ones below. Include two space characters between each + and - character.
Have to use array and cannot call string method charAt.
Hint provided was to use boolean array of length n.
This is my current code:
public class ThueMorse {
public static void main(String[] args) {
int n = Integer. parseInt(args[0]);
String[] tm = {"0", "1"};
tm[0] = "0";
tm[1] = "1";
for (int k = 1; k <= n; k++) {
String t = tm[0];
String m = tm[1];
tm[0] += m;
tm[1] += t;
}
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
if (tm[0].charAt(i) == tm[0].charAt(j))
System. out. print("+ ");
else
System. out. print("- ");
}
System. out. println();
}
}
}
