second tab

third tab
i have collatz values of
int collatzValue(int n) {
      int total = 0;
      for (int i = n; i>1 ; total ++) {
            if (i%2==0)
                  i =(1/2);
            else
                  i = i*3+1;
      }
      reture total;
}

the size is also 300,300

i want it to look like the the image
