Problem:
A linked list is given such that each node contains an additional random pointer which cocould point to any node in the list or null.
Return a deep copy of the list.
The node is defined as follows:
/*** Definition for singly-linked list with a random pointer.* Class randomlistnode {* Int label;* Randomlistnode next,
We've seen Python's most basic mathematical operations in Python operations. In addition, the math package complements more functions. Of course, if you want more advanced math, consider selecting NumPy and scipy projects outside of the standard library, which not only support array and matrix operations, but also rich mathematical and physical equations to use.
In addition, the random package can be used to generate

The method of random number provided by C Srand and Rand, the former is to give the latter set of random number seed seeds.
int rnd_num = 0;
Srand (seed); Time (NULL) usually used to make seeds
Rnd_num = rand (); Generate random numbers
Methods of producing seeds:
1. Use Date Time
Time as a seed is very simple, take the current date and time, but there is a
