Course Introduction:An asynchronous request means that after the client sends a request message, it does not wait for the server's response and continues to perform other operations. Web applications using Ajax technology can quickly present incremental updates to the user interface without the need to reload (refresh) the entire page, which allows the program to respond to user operations faster.

Course Introduction:We will use a for loop to iterate over the array. We will initialize a variable called "result" with the value of the first element in the array. For each subsequent element in the array, we will use the XOR operator to update the "result" value of that element. This process continues until all elements in the array have been processed, and the result is the final XOR value of all elements in the array. Let’s first understand what XOR is. We will also see how the XOR operation on arrays works. Array XOR The XOR (exclusive OR) operation is a bitwise operation that compares two binary numbers and returns 1 if they are different and 0 if they are the same. The XOR operation on an array is a method of combining the values of all elements in an array using the XOR operation. in size

Course Introduction:System exceptions refer to abnormal situations or errors that occur during program execution. When an error or abnormal situation that cannot be handled is encountered during program execution, the system cannot continue normally. System anomalies can be divided into two situations, one is hardware anomaly, and the other is software anomaly. Hardware anomaly refers to an abnormal situation caused by the failure or damage of computer hardware equipment. Software anomaly refers to an error or error in the software program itself. Exceptions caused by exceptions.

Course Introduction:XOR, or exclusive OR, is a Boolean logic operation used to generate parity bits for error checking, fault tolerance, etc. Various symbols are used to represent this operation: ^, ⊕, ⊻, etc. XOR Logic The XOR operation is true only if the two parameters are different. In other words, the XOR of the same bits is 0, and the XOR of different bits is 1. Same bits-0^0=01^1=0 Different bits-0^1=11^0=1 Problem Statement Given two numbers a and b, find them after making the lengths of their binary representations equal XOR. Tip − By adding a trailing zero after the smaller number, the binary representation will become equal. Example input-a=10, b=5 output-0 indicates that the binary representation of 10 is 1010, and the binary representation of 5 is 101. will trail
