Write the program for encrypting/decrypting the text. Read from the standard input the sentance and place the letters in 2-dimensional square table (n = m) most matched to the length of the sentence, e.g. for 14 characters n = 4. For simplicity, let us assume that the sentence has less than 64 characters (table size=8x8). Free cells in the table will be complemented by random letters. Then turn the array, in accordance with the clock and write out the sentance row by row
