WebNote: The bad-character shift can be negative. Since for shifting the characters, the Boyer-Moore algorithm applies the maximum (skip characters) between the good-suffix shift and bad-character shift. Good-Suffix Shift. Let, t substring matched by inner loop, then skip characters until: There are no mismatches between P and t. P moves past t.
