This is my solution to the #scratchbootcamp esreveR and TacocaT challenges. esreveR Create a custom block that takes a string as input, reverses the order of the letters in the string, and stores the output in a variable. Add a code comment explaining how your block works. TacocaT Create a sprite that can detect whether a string is an alphanumeric palindrome. (If you chose to accept this challenge, you may find it helpful to first complete the previous exercise.)
