How to program the shortest path
Press “clear” to eraseTo create a new path,
adjust the length by using the blue sliderspress the "forward", "back", or "turn" buttons
to have it placed in the programming areaClick “draw” to make it draw

What numbers occur most frequently in the ciphertext?
Frequency analysis is the process by which the frequency of a letter in an encoded messages is compared with the frequency of letters in English words.

What numbers occur most frequently in the ciphertext?
For instance, the letter E occurs most often in English words, so if the letter W occurs most often in ciphertext, then it is likely that E has been replaced by W.
