HCN3D - The God-land
English | Tiếng Việt |
How great is our God! To show the respect for God, Bethlehem people decide to build a large area for memorial called "The God-land". There's a story that God used to visit N areas which is rectangles having edges paralell to the axises, described by the co-ordinate of a pair of opposite vertices: Xi1, Yi1, Xi2, Yi2 (any two of them may have no common point, one common vertex or one common edge at most); on which of them there is a kind of grass called Ci. People there want to build the God-land which is also a rectangle having edges parallel to the axises, putting on area(s) mentioned above, having a same kind of grass and having the maximum area! Help them to find the God-land before this Christmas!
Input
- The first line contains N.
- Next N line(s), each line contains Xi1, Yi1, Xi2, Yi2 and Ci describing the ith area to which God used to visit.
Output
- The maximum area found.
