The power of regular expressions cannot be underestimated. Just a few characters often outperform dozens of lines of code, greatly simplifying our redundant code. In the past, many regular expressions were used in JS. Today, I am familiar with the

Suppose you need several possible values for a variable, then it can be defined as an enumeration type. The reason for enumeration is to enumerate the possible values of variables or objects.For example, to make everyone more clear, for example,

Question: The number of Suffixes in string 1 and the lcp of a Suffix in string 2 are k Train of Thought Analysis: First, find the number of logarithm with a length of at least k. Then find out the number of values at least k + 1. Then

The problem is described as follows: Given a linked list, return the node where the cycle begins. If there is no cycle, return null.   Follow up: Can you solve it without using extra space?   From the perspective of the problem, it is not difficult
