Find first set

In computer software and hardware, find first set (ffs) or find first one is a bit operation that returns the index or position of the least significant 'one' bit in its argument, counting from the least significant bit. A related operation is count trailing zeros (ctz) or number of trailing zeros (ntz), which counts the number of zero bits following the…
