. Integer power of a value
Question: implement the function Double Power (double base, int exponent) to calculate the power of base's exponent.Overflow is not required.
Analysis: this seems simple. Some people may write the following code 30 seconds after they see the question:Double Power (double base, int exponent){
Double result = 1.0;For (INT I = 1; I Result * = base;Return result;}
// You need to consider more double power (double base, int exponent) {If (exponent = 0) return 1; double resu

function can be thought of as multiple asynchronous operations, packaged into a Promise object, and the await command is then the syntax of the internal command of the sugar.3, async the function returns a Promise object, you can then add a callback function using the method. When the function executes, it returns when it is encountered, waits for the await asynchronous operation to complete, and then executes the statement behind the function body.function Getstockpricebyname (name) { var sym

After the lecture, immediately on the written test, the subject of the written examination is not difficult. This is not a topic that is revealed online. But the style is like this. It is not difficult to have two big questions. But the written test time is only one hours. The last big question is similar to:

Time Complexity Analysis:
The outer layer needs n-1 cycle, the inner layer for each character, are traversed by the middle to each side, for N, so the total time complexity of O (n * N)

Topic Description:Enter a string that outputs the maximum length of the symmetric substring in the string.For example, the input string "Google", because the longest symmetric substring in the string is
