Have a loop that that checks if the dictionary contains "a", if not, check if it contains "ap" and so on... when found in the dictionary, substring the input string starting from the character after the matched word.

I think there is a more complicated answer to this question. The difficulty of this question is that if the string contains words that if cut in the wrong place may turn the remaining part of the sting without a match from the dictionary. The best answer I know of for this question involves dynamic programming. Google it.
