3.4) Determine the O, 22 and (if possible) D classification of the following code segments (which are written in generic pseudo-code): n = read int() A = array[1 ..n] B = array [1 ..n] for i=1 to n: A[i] = read_int() for i = = 1 to n: B[i] = read_int () for i = 1 to n: for j = 1 to n: print A[i] +B[j]
