第一题不会，第二题82，然后超时 # coding: utf-8 n = int(input()) data = [] data_set = [] total = 0 for i in range(n):     tmp = list(map(int, input().split()))     data_set.append([min(tmp[0], tmp[2]), min(tmp[1], tmp[3]), max(tmp[0], tmp[2]),max(tmp[1], tmp[3])])     total += (abs(tmp[0] - tmp[2]) + 1) * (abs(tmp[1] - tmp[3]) + 1)     data.append(tmp) for i in range(n - 1):     ax1, ay1, ax2, ay2 = data_set[i]     for j in range(i + 1, n):         bx1, by1, bx2, by2 = data_set[j]         x_len = max(0, min(ax2, bx2) - max(ax1, bx1) + 1)         if x_len == 0:             continue         y_len = max(0, min(ay2, by2) - max(ay1, by1) + 1)         if y_len == 0:             continue         total -= x_len * y_len print(total)
