java - Rotate a given String layout clockwise -


given string layout of following form:

x......x ....x..x ....x..x

rotate above layout 90 degrees clockwise should be:

..x ... ... ... xx. ... ... xxx

what's easiest way rotate string characters clockwise 90 degrees? string layout can of form , size. if have 100000x100000 size string layout?

public string rotate(string layout)

or

public void rotate(string layout)

edit

i fixed mistake pointed out op in comments below. should produce required in original question above.

 public static string rotatestringmatrixby90(string matrix) {     int numberofrows = 3; // leave exercise     int numberofcolumns = 8; // same 1      string newmatrix = "";      int count = 0;     string[] newmatrixcolumns= matrix.split("\n");     while (count < matrix.split("\n")[0].length()) {         (int = newmatrixcolumns.length - 1; > -1; i--) {             newmatrix = newmatrix + newmatrixcolumns[i].charat(count);         }          newmatrix = newmatrix + "\n";         count++;     }      return newmatrix;  }

and how use it:

    string m = "x......x\n" +                "....x..x\n" +                "....x..x";      system.out.println(m);      m = rotatestringmatrixby90(m);     system.out.println(m);

(note: assumes using \n separator between rows):

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
