In textbooks the XOR operator is denoted by ⊕, but in most challenges and programming languages you will see the caret ^ used instead. For binary strings we XOR bit by bit: b'0110' ^ b'1010' = b'1100' . http://www.crypto-it.net/eng/theory/modular-arithmetic.html

WebIn modular arithmetic this operation is equivalent to a square root of a number (and where x is the modular square root of a modulo p ). For example, if we have a = 969 and p = 1223, we get: x 2 = 968 ( mod 1223) For this we get a solution of: 453 2 = 968 ( mod 1223) If we have a = 1203 and p = 1223, we get: x 2 = 1203 ( mod 1223) WebMar 31, 2015 · Modular arithmetic (clock arithmetic) is a system of integer arithmetic based on the congruence relation a ≡ b ( mod n) which means that n divides a − b.
