We tackle this problem and a few similar ones in this video. We realise that there are two ways to solve these problems. Slower method involves listing down all possible arrangements and then manually hunting down the word we're looking for. This is tedious and prone to errors. A much faster method is to calculate the number of words starting with first letters. This helps us navigate the dictionary neatly.
