In a word builder you are given a word which you have to transform into a bigger word in a series of steps. With each step you can rearrange the letters and either add a new letter or swap a letter already in the word for a different one. Each step must form a common
English word. The objective is to get to the bigger word from the smaller word in the least number of steps.
Try to change RED to SCARLET in the smallest number of steps.
