Question:Console. Log ();VaRA = 1; Console. Log ();FunctionA () {console. Log (2);} Console. Log ();VaRA = 3; Console. Log ();FunctionA () {console. Log (4);} Console. Log (a); ();Running result:Analysis:Multiple variables and function declarations in the question will be improved, and the priority of the function is higher than that of the variable. The two function declarations are later than the previous ones, so the first a isF A () {console. Log

Problem: When writing a mul function call, the following output is generated:Console.log (Mul (2) (3) (4)); Output:24Console.log (Mul (4) (3) (4)); output:48Answer: Time allowed This should be the answer the Lord wants, and it supports any number of calls. It mainly investigates the understanding of recursion, and the use of valueOf.function mul(x) {const result = (y) => mul(x * y); result.valueOf = () => x;return result;}console.log(mul(3))-> 3console.log(mul(3)(2))-> 6console.log(mul(3)(2)(4))

Title Requirements:Enter an array of integers, adjusting the order of the numbers in the array so that all the odd digits are in the first half of the array, and all the even digits are in the second half of the array.Requires a time complexity of O (n).Reference: Sword refers to the 14th question of offer.Topic Analysis:Using two pointers, Pbegin and pend,pbegin traverse backwards from the beginning, pEnd forward from the end, and when Pbegin encount

the array is adjacent, that is, we allow to find a number (A[i],..., a[n-1],a[0],..., a[j]), please make it and maximum, what to do? Answer: Programming Beauty 2.14 Expansion problem, also can be seen this blog post-sequence programming beauty series. Hint: Adopt three variables: max,min,sum;Max: Sum of the largest subarray; min: Sums of the smallest sub-arrays; sum: total of the arraysThe last to take Max and Sum-min is to ask for the big person. Extension 2: There is an integer

(One interview question) thread and thread I. Main advantages of multithreading: improved efficiency. But thread security exists. The Code is as follows: Realistic multi-Thread method: implements the Runnable interface and inherits the Thread class (Generally, the Runnable interface is implemented mainly because java does not support multiple inheritance. Once you inherit the Thread class, you cannot inheri

space lattice, front and back no space.The returned result is to reverse the alphabetic order of each word, but the order of words and the uppercase and lowercase positions of letters remain unchanged. Example:Input parametersThis is an Apple on eBayReturnSiht si na Elppa no yAbe(For example, because eBay is the second letter in upper case, keep the second letter in upper case after being reversed .) My program: $value){$str_arr[$key] = getNewStrExtra($value);}$new_str = implode(' ',$str_arr)

Since a number disappears, there must be a number that appears once and the other numbers appear even several times. It is not necessary to use the search to do, using the two characteristics of the XOR operation--1. Self-XOR or result 02. Different or satisfy the Exchange law.So we're going to have these numbers all different or again, and the result must be that number that only appears. The sample code is as follows:Int[] Arra = {11,12,3,12,11,12,12};Static voidMain (string[] args) {

the first number and the last number [TestMethod] publicvoid GetMinNumTest3 () { int 3 4 5 1 2 2 }; 1 ); }(4) There are duplicate numbers, and the number of repetitions is exactly the first and last number. // There are duplicate numbers, and the number of repetitions is exactly the first number and the last number .
