L2 = underroot sigma n i = 1 (ai - bi)2 Assume a and b are two (20, 20) numpy arrays. The L2-distance (defined above) between two equal dimension arrays can be calculated in python as follows:
def 12_dist(a, b):
result ((a - b) * (a - b)). sum)
result = result ** 0.5
return result
Which of the following expressions using this function will give an error?
a. 12_dist(np. reshape(a, (20 * 20)), np. reshape(b, (20 * 20, 1)))
b. 12_dist(a, b)
c. 12_dist(np. reshape(a, (20 * 20)), np. reshape(b, (20 * 20)))
d. 12_dist(a. T, 5.1)

3. (5 points) describe what would be printed by the code below or what error would occur. const char* cstr = "0123456"; const char* ptr = & cstr[4]; cout < < ptr[-1] < < ptr < < endl; 1 4. (5 points) theseus has been trapped in a maze with a minotaur, which is trying to capture him. each round, theseus and the minotaur move through the maze; theseus towards the exit, and the minotaur towards theseus. theseus can move in any of the four cardinal directions, or he can wait for a round to see how the minotaur moves. write code that creates a data type to represent the possible moves that theseus could make.
