Create a spreadsheet that takes eight values that a user inputs into eight different cells. Then create a row that transposes the cells to simulate a transposition cipher, using the example transposition cipher from the text. Remember to work from right to left, with the pattern 1 > 3, 2 > 6, 3 > 8, 4 > 1, 5 > 4, 6 > 7, 7 > 5, 8 > 2 where 1 is the rightmost of the eight cells. Input the text ABCDEFGH as single characters into the first row of cells. What is displayed?
