牛客网-贪心-裁减网格纸

https://www.nowcoder.com/questionTerminal/65865c6644154bb4acca764b1480ecbb?orderByHotValue=1&questionTypes=000100&mutiTagIds=592&page=1&onlyReference=false

度度熊有一张网格纸，但是纸上有一些点过的点，每个点都在网格点上，若把网格看成一个坐标轴平行于网格线的坐标系的话，每个点可以用一对整数x，y来表示。度度熊必须沿着网格线画一个正方形，使所有点在正方形的内部或者边界。然后把这个正方形剪下来。问剪掉正方形的最小面积是多少。

输入描述:

第一行一个数n(2≤n≤1000)表示点数，接下来每行一对整数xi,yi(－1e9<=xi,yi<=1e9)表示网格上的点

输出描述:

一行输出最小面积
