On the Subject of Red Button’t

Red cube button.

On the module, there is a red button and a screen flashing different words.

Step 1:

Note down the word before the word ‘SUBMIT’ and remove any duplicate letters from the word, keeping each letter’s first occurrence. Then take the alphabet (without Z) and remove any occurrences of all the letters in your word. Lastly, place the alphabet at the beginning of your word. If there are 26 letters, remove the last one in the string. Fill the string into a 5x5 matrix.

Step 2:

Note down the letters on the red button. The first letter is the start location and the second one is the end location in the matrix from the last step. Holding and releasing the button will perform an action on the current position. You can hold the button at any time.

Releasing the button when the display shows the word “SUBMIT” will submit your current position.
Releasing the button when the display shows a direction will move your current position one cell in that direction.
Releasing the button when the display shows the word “RESET” will reset your current position.
To solve the module, move the current position to the end position and submit. The matrix doesn't wrap around.
