Spelling a word backwords

For all of the following words, if you move the first letter to the end of the word, and then spell the result backwards, you will get the original word: banana dresser grammar potato revive uneven assess

I got the first part down, moving the first letter to the end, but I am not able to spell the word in reverse. I have to use a for loop for this, but I have no idea how to use it so it will spell the rest of the word backwards.

Solution

  • Normally the for-loop does not care in which way you modify the index, so you should be able to use something like

    string firstAtLast = "otatop";
string reverse = "";

for(int i=string.length-1; i => 0; i--)
{
    reverse += firstAtLast.At(i)
}

    Details for i and the string manipulation methods depend on your language of course.
