' n) J/ ^5 V) l! P) o- F公仔箱論壇将比较重的那份再平均分成两份成一次
. S! l* W  _; p  s, L' E5.39.217.76剩下3个随意拿两个来称,如果天平平衡就是第三个,如果不平衡就是重的那个

第一次系一边四个,一边四个秤既
1 - compare 4 with 4) N7 t: n- T  ?# G+ A
if  (4v4)= same that means the rest of 4 is got more weight: ]$ R6 e5 ~3 H" j( C- F; l$ K
    then goto 2 - compare rest of(4)  - 2 with 2 5.39.217.76: u8 w/ y4 X6 v0 y- S
           if (left side is more weight)( |+ ?, B! s7 Y3 t: P6 i
              then goto 3 - compare last (left side of ( 2) - 1 with 1 => get answertvb now,tvbnow,bttvb0 b# {9 c$ \( ~! n; p$ [: z
          else ( right side is more weight)5.39.217.76/ w. H) `) {8 m
              then goto 3 - compare last (right side of (2) - 1 with 1 => get answer
8 Z2 @6 R* J! n, Felse ( the left 4) then compare with above  , or right 4 also can compare above method...
想了好久都不行
我的做法与4楼的做法一致,这样应该可以排除出来。但这个题目有个漏洞,只说重量异常,没说是重了,还是轻了。
