WebSuppose we wish to find the lowest set bit of x (which is known to be non-zero). If we subtract 1 from x then this bit is cleared, but all the other one bits in x remain set. I don't understand how this statement is true. If we take x = 110, subtracting 1 would give 101. Here, the lowest set bit is not cleared.
