WebFeb 27, 1996 · Naive string matching: for (i=0; T [i] != '\0'; i++) { for (j=0; T [i+j] != '\0' && P [j] != '\0' && T [i+j]==P [j]; j++) ; if (P [j] == '\0') found a match } There are two nested loops; the inner one takes O (m) iterations and the outer one takes O (n) iterations so the total time is the product, O (mn). This is slow; we'd like to speed it up.
