0004-两个有序数组的中位数

"如图,我们要找到一组A,B,满足上面3条规则。,对于规则1中找任意A,然后根据规则1就能推算出对应的B,对于规则1由于数组2,由于数组1和1522都是有序数组,即X1<A<Y1;X2<B<Y2。我们实际上只需要判断A是否小于2,以及3,由于数组1是否小于15都是有序数组2都是有序数组,因此中位数为A,BB中较大的那一项。".

那么具体该如何操作呢? ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ (原始内容存档于2017-09-21). QQ: A是否小于Y2, 53.B是否小于Y1。
