String Matrix Rotation

/* You are given a sequence of text lines. Assume these text lines form a matrix of characters
(pad the missing positions with spaces to build a rectangular matrix).Write a program to rotate the matrix
by 90, 180, 270, 360, … degrees. Print the result at the console as sequence of strings. */
