In this programming tutorial we will find XOR of 1 to n.
About XOR operator
XOR operator is a binary operator and it gives us 1 for odd number of 1s and 0 for even number of 1s.
In programming XOR is represented by
^ caret symbol.
We also represent XOR with this
⊕ plus inside circle symbol.
Following is the truth table for the XOR operator.
| A | B | A^B |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Remember!XOR of odd 1s = 1XOR of even 1s = 0
