# Logic Gates in Python

# The AND gate gives an output of 1 if both the two inputs are 1, it gives 0 otherwise
def AND(x: int, y: int) -> int:
    if x == 1 and y == 1:
        return 1

# The OR gate gives an output of 1 if either of the two inputs are 1, it gives 0 otherwise
def OR(x: int, y: int) -> int:
    if x == 1 or y == 1:
        return 1
    return 0

# It acts as an inverter. It takes only one input. If the input is given as 1, it will invert the result as 0 and vice-versa
def NOT(x: int) -> int:
    if x == 1:
        return 0
    return 1

# The XOR gate gives an output of 1 if either of the inputs is different, it gives 0 if they are the same
def XOR(x: int, y: int) -> int:
    if x != y:
        return 1
