## What is XOR value?

XOR is one of the sixteen possible binary operations on Boolean operands. That means that it takes 2 inputs (it’s binary) and produces one output (it’s an operation), and the inputs and outputs may only take the values of TRUE or FALSE (it’s Boolean) – see Figure 1.

**How is XOR calculated?**

To find XOR of more than two numbers, represent all numbers in binary representation, add 0’s before if necessary. Write them like this. and so on. To find each bit of XOR just calculate number of 1’s in the corresponding bits.

**What does XOR do to a number?**

This is based on the simple fact that XOR of a number with itself results Zero. and XOR of a number with 0 results the number itself. So, if we have an array = {5,8,12,5,12}.

### What does XOR stand for?

eXclusive OR

X. (eXclusive OR) A Boolean logic operation that is widely used in cryptography as well as in generating parity bits for error checking and fault tolerance. XOR compares two input bits and generates one output bit. The logic is simple. If the bits are the same, the result is 0.

**What is XOR example?**

Examples: 1 XOR 1 = 0. 0 XOR 1 = 1. 0 XOR 0 = 0. 11102 XOR 10012 = 01112 (this is equivalent to addition without carry)

**What is maximum XOR value?**

Bit representation of 1 = 001. Now, you can see that after selecting as much numbers you want and selecting any of them you can not obtain XOR value greater than 111 i.e 7. So, for a given n and k >1 the maximum possible XOR value is 2log2(n)+1-1 (that is the value when all bits of n are turned to 1). Java.

#### What is the XOR problem?

The XOR, or “exclusive or”, problem is a classic problem in ANN research. It is the problem of using a neural network to predict the outputs of XOR logic gates given two binary inputs. An XOR function should return a true value if the two inputs are not equal and a false value if they are equal.

**How do you reverse XOR?**

XOR, however, can be reversed if and only if you define a decryption key which in case of your question, it is not applicable. The best practice to merge two sets of numbers and still be able to get back the original data can be done by creating a 2 linear and 2 unknown equation.

**What is a logical XOR?**

A connective in logic known as the “exclusive or,” or exclusive disjunction. It yields true if exactly one (but not both) of two conditions is true. The XOR operation does not have a standard symbol, but is sometimes denoted (this work) or. (Simpson 1987, pp.

## What is a XOR 1?

XOR is a logical operator that works on bits. Let’s denote it by ^ . If the two bits it takes as input are the same, the result is 0 , otherwise it is 1 . This implements an exclusive or operation, i.e. exactly one argument has to be 1 for the final result to be 1 .

**How do you get max XOR?**

So, for a given n and k >1 the maximum possible XOR value is 2log2(n)+1-1 (that is the value when all bits of n are turned to 1).

**What is maximum XOR Subarray?**

For example if i=2 in {8, 2, 1, 12}, then the maximum subarray xor ending with arr[2] is the whole prefix. If we do XOR of such previous prefix with current prefix, we get the maximum XOR value ending with arr[i]. If there is no prefix to be removed (case i), then we return 0 (that’s why we inserted 0 in Trie).
