If you use copy.deepcopy(), it's like building an exact replica from scratch. Every single element, even the ones deep inside, is brand new. It's like creating a clone that has no connection to the original at all. - 哦,要在Python里真正复制一个复杂的数据结构,copy.deepcopy()就是...
There is only one duplicate number in the array, but it could be repeated more than once 非常好的题目,开始是用二分做的,比如取数组为{1,2,3,3,4,5},mid应该是(5+1)/2 = 3,那么,如果小于等于mid的数的个数如果超过了3,那么重复的数字一定出现在l,mid之间,否则出现在mid + 1,r之间。以该...
