WebbFind A sub four. So let's write this down. They're telling us A sub zero is equal to two and they also tell us that A sub one is equal to three. So they've kind of given us our starting conditions or our base conditions. Now we can think about what A sub two is. They tell us that A sub two is going to be A sub two minus one, so that's A sub one. Webb11 maj 2014 · The recursive function signature would be like: boolean search (string word, int direction) with terminal case if (word.length==1) return isNextLetterInDirection (word, direction); and the search being search (substring (word, 0, word.length-1), direction); This algorithm also cover palindrome cases and words including their syllables.
