The C function funsum below takes three arguments -- an integer val and two function pointers to functions f and g, respectively. f and g both take an integer argument and return an integer result. The function funsum applies f to val, applies g to val, and returns the sum of the two results. Translate to RISC-V following RISC-V register conventions. Note that you do not know, nor do you need to know, what f and g do, nor do you know what registers f and g use.

long long int funsum(long long int val, long long int (*f) (long long int), long long int (*g) (long long int))

{

return(f(val) + g(val));

}

The coordinates of an object moving in the xy plane vary with time according to the equations x = −5.08 sin ωt and y = 4.00 − 5.08 cos ωt, where ω is a constant, x and y are in meters, and t is in seconds.

(a) Determine the components of velocity of the object at t = 0. (Use the following as necessary: ω.) v with arrow = m/s

(b) Determine the components of the acceleration of the object at t = 0. (Use the following as necessary: ω.) a with arrow = m/s2

(c) Write expressions for the position vector, the velocity vector, and the acceleration vector of the object at any time t > 0. (Use the following as necessary: omega for ω and t.) r with arrow = m v with arrow = m/s a with arrow = m/s2

(d) Describe the path of the object in an xy plot.

Usually, Djikstra’s shortest-path algorithm is not used on graphs with negative-weight edges because it may fail and give us an incorrect answer. However, sometimes Djikstra’s will give us the correct answer even if the graph has negative edges.
You are given graph G with at least one negative edge, and a source s. Write an algorithm that tests whether Djikstra’s algorithm will give the correct shortest paths from s. If it does, return the shortest paths. If not, return ‘no.’ The time complexity should not be longer than that of Djiksta’s algorithm itself, which is Θ(|E| + |V | log |V |).
(Hint: First, use Djikstra’s algorithm to come up with candidate paths. Then, write an algorithm to verify whether they are in fact the shortest paths from s.)
