The following C function takes two ASCII strings and determines whether one is an anagram of the other. An anagram of a string s is a string obtained by permuting the letters in s.

int anagram (char *a, char *b) {
int count [128], j;
for (j = 0;  j < 128; j++) count[j] = 0;
j = 0;
while (a[j] && b[j]) {
A;
B;
}
for (j = 0; j < 128; j++) if (count [j]) return 0;
return 1;
}

Choose the correct alternative for statements A and B.
