How would you complete these 3 bit arithmetic functions using only the specified logical operators (Please explain a little I'm trying to get an understanding of this)

int bitOr(int x, int y) { //For this function only use the ~ and & logical operators

return 2;

}

int bitAnd(int x, int y) { //For this function only use the ~ and | logical operators

return 2;

}

int bitXor(int x, int y) { //For this function only use the ~ and & logical operators

return 2;

}
