B"There is a city that can be represented as a square grid with corner points in (0, 0) and (10^6, 10^6) . The city has n vertical and m horizontal streets that goes across the whole city, i. e. the i -th vertical streets goes from (x_i, 0) to (x_i, 10^6) and the j -th horizontal street goes from (0, y_j) to (10^6, y_j) . All streets are bidirectional. Borders of the city are streets as well. There are k persons staying on the streets: the p -th person at point (x_p, y_p) (so either x_p equal to some x_i or y_p equal to some y_j , or both). Let's say that a pair of persons form an inconvenient pair if the shortest path from one person to another going only by streets is strictly greater than the Manhattan distance between them. Calculate the number of inconvenient pairs of persons (pairs (x, y) and (y, x) are the same pair). Let's recall that Manhattan distance between points (x_1, y_1) and (x_2, y_2) is |x_1 - x_2| + |y_1 - y_2| . The first line contains a single integer t ( 1 <= t <= 1000 ) -- the number of test cases. The first line of each test case contains three integers n , m and k ( 2 <= n, m <= 2 cdot 10^5 ; 2 <= k <= 3 cdot 10^5 ) -- the number of vertical and horizontal streets and the number of persons. The second line of each test case contains n integers x_1, x_2, ... , x_n ( 0 = x_1 < x_2 < ... < x_{n - 1} < x_n = 10^6 ) -- the x -coordinates of vertical streets. The third line contains m integers y_1, y_2, ... , y_m ( 0 = y_1 < y_2 < ... < y_{m - 1} < y_m = 10^6 ) -- the y -coordinates of horizontal streets. Next k lines contains description of people. The p -th line contains two integers x_p and y_p ( 0 <= x_p, y_p <= 10^6 ; x_p in {x_1, ... , x_n } or y_p in {y_1, ... , y_m "...
