## How do you find the XOR of all elements in a list?

Therefore, the following steps are followed to compute the answer:

- Create a variable to store the XOR of the array as a result.
- For each element in the array, find the XOR of the element and the result variable using ‘^’ operator.
- Finally, the result variable stores the XOR of all elements in the array.

## How is XOR easily calculated?

To find each bit of XOR just calculate number of 1’s in the corresponding bits. If it is even or zero then that XOR’ed bit is 0. If it is odd then that XOR’ed bit is 1.

**What is XOR of 1 to n?**

1- Find the remainder of n by moduling it with 4. 2- If rem = 0, then xor will be same as n. 3- If rem = 1, then xor will be 1. 4- If rem = 2, then xor will be n+1.

**How do you solve XOR in Python?**

Let’s understand each operator one by one. Bitwise AND operator: Returns 1 if both the bits are 1 else 0. Bitwise or operator: Returns 1 if either of the bit is 1 else 0….Bitwise operators.

OPERATOR | DESCRIPTION | SYNTAX |
---|---|---|

^ | Bitwise XOR | x ^ y |

>> | Bitwise right shift | x>> |

<< | Bitwise left shift | x<< |

### How do you find the XOR of 3 numbers?

Equal Sum and XOR of three Numbers

- Input: N = 2.
- Output: 3. Explanation:- For N = 2. 2 XOR 0 XOR 0 = 2+0+0. 2 XOR 0 XOR 1 = 2+0+1. 2 XOR 0 XOR 2 != 2+0+2. 2 XOR 1 XOR 0 = 2+1+0. 2 XOR 1 XOR 1 != 2+1+1. 2 XOR 1 XOR 2 != 2+1+2. 2 XOR 2 XOR 0 != 2+2+0. 2 XOR 2 XOR 1 != 2+2+1. 2 XOR 2 XOR 2 != 2+2+2.
- Input: N = 4.
- Output: 9.

### What is the inverse of XOR?

XOR stands for eXclusive OR. As can be seen, the output values of XNOR are simply the inverse of the corresponding output values of XOR.

**How do you do XOR of 3 numbers?**

**How do I use XOR in Python 3?**

Bitwise AND operator: Returns 1 if both the bits are 1 else 0. Bitwise or operator: Returns 1 if either of the bit is 1 else 0. Bitwise not operator: Returns one’s complement of the number….Bitwise operators.

OPERATOR | DESCRIPTION | SYNTAX |
---|---|---|

^ | Bitwise XOR | x ^ y |

>> | Bitwise right shift | x>> |

<< | Bitwise left shift | x<< |

## What is the XOR trick?

The XOR trick: If we have a sequence of XOR operations a ^ b ^ c ^ …, then we can remove all pairs of duplicated values without affecting the result. Commutativity allows us to re-order the applications of XOR so that the duplicated elements are next to each other.

## What is XOR linked list?

In the XOR linked list, instead of storing actual memory addresses, every node stores the XOR of addresses of previous and next nodes. Consider the above Doubly Linked List. Following are the Ordinary and XOR (or Memory Efficient) representations of the Doubly Linked List.

**How do you know if XOR is 1 or 0?**

If the two bits XOR takes as input are the same, the result is 0, otherwise it is 1. If we analyze the individual bits in u ^ v, then every 0 means that the bit had the same value in both u and v. Every 1 means that the bits differed.

**How to do XOR in Python?**

Let’s discuss certain ways in which XOR can be performed. Method #1 : Using reduce () + lambda + “^” operator. The above functions can be combined to perform this task. We can employ reduce () to accumulate the result of XOR logic specified by the lambda function. Works only with Python2.
