Question
XORinacci Number
Cengiz created a new sequence called XORinacci numbers. The sequence is defined as follows:
KaTeX can only parse string typed expression
KaTeX can only parse string typed expression
KaTeX can only parse string typed expression for KaTeX can only parse string typed expression
Here, KaTeX can only parse string typed expression represents the bitwise XOR operation.
You are given three integers KaTeX can only parse string typed expression, KaTeX can only parse string typed expression, and KaTeX can only parse string typed expression. Your task is to compute the value of KaTeX can only parse string typed expression.
Input
