Consider the following method that is intended to test if all the strings in the arraylist start with an uppercase letter:
public static boolean capitalized(arraylist a) {
/* missing code */
}
which of the following could replace /* missing code */ so that the method works as intended?
i.
for (string s: a) {
if (s.(0) ! = s. charat(0)) {
return true;
}
}
return false;
ii.
for (string s: a) {
if (s.(0) ! = s. charat(0)) {
return false;
}
}
return true;
iii.
int flag = 1;
for (string s: a) {
if (s.(0) ! = s. charat(0)) {
flag = 0;
}
}
return (flag == 1);
ii only
iii only
i, ii and iii
i only
ii and iii

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.
