If you're familiar with the ? operator x ? y : z you have to implement that in a function: int cond(int x, int y, int z); using only ~, !, ^, &, +, |, <<, >> no if statements, or loops or anything else, just those operators, and the function should correctly return y or z based on the value of x. You may use constants, but only 8 bit constants. You can cast all you want. You're not supposed to use extra variables, but in the end, it won't really matter, using variables just makes things cleaner. You should be able to reduce your solution to a single line in the end though that requires no extra vars.
