addition operation

We continue to analyze the examples in the primary article. In the introductory chapter we use Eclipse to automatically generate a test framework, in this article, we will carefully analyze the test framework of each of the details, know it more to

Common bit Operation implementations1. A common equation:-n = ~ (n-1) = ~n + 12. Gets the integer binary of the rightmost 1:n & (-N) or N & ~ (n-1). For example n = 010100,-n = 101100, then N & (-N) = 0001003. The rightmost 1:n & (n-1) of the binary

Article, Thank you for pointing out the mistakes -->   General declared array: var arr = [1, 2, 3]; Use the apply () method: var arr = array. Apply (null, [1, 2, 3]); Of course, you can also use apply () to create objects.The following is an

Values have positive and negative values, and the computer uses the highest bit of a number to store the symbols (0 is positive, 1 is negative ). this is the original code of the number of machines. assume that the number of digits processed by the

In JavaScript, the rule of addition is actually simple, in only two cases: Add numbers and Numbers Add a string and a string All other types of values are automatically converted to these two types of values. In order to figure out

Recently encountered a problem that is difficult to solve; a simple JS addition operation expression:1 // add an empty array here to get what???Answer: ' 1 ';Why the answer is 1, I was very confused at first; I read an article before I learned that

After the first example of the design pattern, I once again realized that building a software is not only for function implementation, but also for "serving the people "! You do not need to use object-oriented methods to write data. To implement a
