I receive the following Valgrind error when trying to run ./Nine20 2 2 100 -123 123-

==3154== Command: ./Nine20 2 2 100 -123 123-
==3154== 
==3154== Conditional jump or move depends on uninitialised value(s)
==3154==    at 0x483BBE9: strlen (vg_replace_strmem.c:461)
==3154==    by 0x4017A3: main (Nine20.c:143)

For context, these are the relevant lines of code

// remove the position P at the head of the queue
    char *p;
    remD(&d, &p);
    searchH(h, p, &reached_from, &n);
    int p_len = strlen(p);

I'm calculating p_len so that I can iterate over the characters of p to find out where '-' is.
