There are two monotonically increasing sequence, a sequence of N integers, the second sequence of M integers, you can now one the first sequence number x, then the second sequence selected a number y, So how many cases meet x+y < = K it? Input contains multiple sets of data. For each set of data, the number of cases to meet output x+ y < = K. For each set of data, the number of cases to meet output x+ y < = K.
