Problems in implementing deep copy using JSON method
In today’s front-end interviews, deep copies appear very frequently. Among the general questions, you may first be asked, what is deep copy, and what are the ways to implement deep copy? You may answer a few points, such as through JSON.strinfy and JSON.parse provided by the JSON object, because this This implementation method is extremely […]
System.arraycopy for array copy
In order to test the difference between the two, I wrote a simple program that assigns int[100000] for comparison, and used nanoTime to calculate the time difference: The procedure is as follows: int[] a = new int[100000]; for(int i=0;i<a.length;i + + ){ a[i] = i; } int[] b = new int[100000]; int[] c = new […]

5. Deep copy and shallow copy + return value optimization
Deep copy and shallow copy + return value optimization Concept In C++, deep copy and shallow copy are two different methods of object copying, and they show different behaviors when dealing with dynamically allocated memory. Shallow Copy: Shallow copy refers to copying the value of the data member of one object to another object, but […]
