Suppose you have an alphabet for patterns that includes a ‘gap' or wild-card character; any length string of any characters can match this additional character. For example if ‘_' is the wild-card, then the pattern ‘foo*bar*nad' can be found in ‘foofoowangbarnad'. Modify the computation of the prefix function to correctly match strings using KMP.
