Mathematical mind
Write a max function without using any conditional statements.
union FloatUint
{
float f;
uint32_t n;
};float max(float a, float b)
{
float t[2] = { a, b };
FloatUint c;
c.f = a - b;
return t[c.u >> 31];
}float max(float a, float b)
{
return (a + b) / 2 + abs((a - b) / 2);
}Write a program that takes an input x and returns 1 if x is 2, and 2 if x is 1.
return 3 – x;
or
return x XOR 3;
