已知TEwTEwTAwDAxTAwTAxDEw这样排列,T=1或者0,E=1或者0,E=1或者0,A=1或者0,w=1或者0,x=1或者0,请问有几种排列方式,分别是什么,怎么算。
序列TEwTEwTAwDAxTAwTAxDEw里,不管T、E、w、A、D、x分别出现多少次,同一时刻每个字母都仅等于一个数字(0或者1)。没有其他限制的话,总共6个字母,每个有0和1两种可能,这样实际上就有2^6即64种组合。
相应的,字符串所有组合只需要将每组字母代表数字代入字符串即可,如下:
000000000000000000000
000000000001000001000

这里使用VBA进行处理,如下代码供参考:
Sub T()
Dim ii%, T%, E%, w%, A%, D%, x%
ii = 1
For T = 0 To 1
For E = 0 To 1
For w = 0 To 1
For A = 0 To 1
For D = 0 To 1
For x = 0 To 1
Cells(2, ii + 1) = T
Cells(3, ii + 1) = E
Cells(4, ii + 1) = w
Cells(5, ii + 1) = A
Cells(6, ii + 1) = D
Cells(7, ii + 1) = x
Range("A" & ii + 10).NumberFormatLocal = "@"
Range("A" & ii + 10) = T & E & w & T & E & w & T & A & w & D & A & x & T & A & w & T & A & x & D & E & w
ii = ii + 1
Next x
Next D
Next A
Next w
Next E
Next T
End Sub
以上,希望能帮上忙!
