Answer in C++ only In order to expand its reach to the outer universe and ensure universal peace, the MIB has decided to expand its offices. Namely, it has established its office on NN most important planets in the universe, with the base station on the planet S. Each office has an intergalactic teleporter that connects it to other planet offices. But the teleporters are bound to a planet's policy, so you cannot teleport to any planet you wish. Due to intergalactic feuds, the planets are divided into KK different alliances, numbered 1 through KK. You know for each planet i, the alliance that it belongs to. In other words, you're given a sequence A1,A2...,An, which says that planet ii belongs to alliance A_{i}. Each planet ii has a policy of teleportation to the planets of other alliances: Cost to travel from one planet to another is determined by the alliance of the destination planet. More formally, the cost to reach a planet which belongs to alliance j from planet ii is represented…

Suppose we're modelling an RC crane which is receiving a sequence of input commands, each of which is UP, DOWN, or BEEP. This crane has only two vertical positions, and starts in the high position. It should go into an ERROR end state if it is asked to go UP when it is in the high position or DOWN when it is in the low position. Once it is in the ERROR state, it stays in the ERROR state no matter what commands it receives. BEEP commands are legal at any point. Give a state diagram for this system, in which each edge corresponds to receiving a single command.
Part a. Make a diagram of memory for point one when n == 2. int expo(int x, int n) { int r, t; if (n == 0) r = 1; else if (n == 1) r = x; else { t = expo (x, n / 2); r = t * t; if (n % 2 == 1) r *= t: } //-- -point one return r; int main(void) { int i; i = expo(4, 5); return 0; Part b. Using divide-and-conquer recursion to solve a problem similar to Prob- lem 3 is somewaiät tricky but a good test of programming skill. Write a function definition that provides a divide-and-conquer implementation of the following interface: double max_adj_sum(const double *a, int lo, int hi); // REQUIRES: hi - lo >= 2. // PROMISES: Return value is the largest sum that can be made by adding // Elements a[lo] ... a[hi -1] exist. two elements among a[lo] ... a[hi-1] with adjacent inderes. Hint: It makes sense to have two base cases, not just one.
