4 vs 4, two case => a)same or b)diff.公仔箱論壇0 d4 H2 s6 t8 h: z" K" f, l) V
a)the not weighted 4 have the target, take 3 to weight with normal => same=the forth is target, diff. can let us know the target is heavy or light, weight two of those contain the target will let us know the answer + c) D5 S# i' y2 i
b)diff. result will have light and heavy again 4vs 4, C vs D C=(3 normal + 1 heavy), D=(3 heavy + 1 light) => again 2 case same or diff., For diff. if C is heavier, than the target is that put in C, if D heavy, the 3 heavy can be weighted with 1 vs 1, heavy one is the target... For same, the target is in that 3 lighter ones, weight them 1 vs 1 will let u know the answer... |
