Consider the following string match function that extracts a substring from the length of the pattern P in the string text T. It works for the pattern "why" and the text "whysaywhycatwhy" but fails with the text " why say why cat why" for the same pattern. Why does the "dum" string match function fail?
void dum(String P, String T) { int N = T.length()-1; int M = P.length(); int start = 0; while(start < N){ String extract = T.substring(start, start+M); if(extract.equals(P)) System.out.printf("Match at %d%n",start); start = start + M; } } a. The dum() function fails because it does not consider the overlap of the pattern within the extracted substring b. The dum() function fails because it does not preprocess the string text c. The dum() string match function fails because it does not hash efficiently d. The dum() string match function fails because of the whitespace characters
