Can someone tell me where is wrong with my output?

Thanks.

The problem description says:

There has to be exactly one column of blanks between two digits.

[Sherman MXF]

Sorry, i found my array "scr" is too small...

[Melon Melon]

i get WA for this Qs..
i wonder what is the meaning of

Be sure to fill all the white space occupied by the digits with blanks, also for the last digit.

where the "last digit"... is it needed special manipulation on it??
i just treate it as usual digits..can i?????

[10153EN]

This is to fill all the white space occupied by the digits with blanks, also for the last digit:


[c]
bbbbbb--bbb--bbbbbbbb--b
bbb|bbbb|bbbb|b|bb|b|bbb
bbb|bbbb|bbbb|b|bb|b|bbb
bbbbbb--bbb--bbb--bbb--b
bbb|b|bbbbbbb|bbbb|bbbb|
bbb|b|bbbbbbb|bbbb|bbbb|
bbbbbb--bbb--bbbbbbbb--b
[/c]

This is to fill all the white space occupied by the digits with blanks, but not the last digit:

[c]
bbbbbb--bbb--bbbbbbbb--
bbb|bbbb|bbbb|b|bb|b|
bbb|bbbb|bbbb|b|bb|b|
bbbbbb--bbb--bbb--bbb--
bbb|b|bbbbbbb|bbbb|bbbb|
bbb|b|bbbbbbb|bbbb|bbbb|
bbbbbb--bbb--bbbbbbbb--
[/c]

where b is the blanks.

Hope can help~

[xenon]

In the last digit also fill then 'unused space' at the end of the line with blanks:

Code: Select all

bbbn
bb|n
bbbn
bb|n
bbbn

b-bn
bb|n
b-bn
|bbn
b-bn

etc.
not:

n
bb|n
n
bb|n
n

b-n
bb|n
b-n
|n
b-n

here 'b' is a blank, 'n' is the end of line.

We were writing replies simultaniously

[10153EN]

Haha... yes, and the idea of both messages are the same~

[Melon Melon]

ths both..
...
i ve dealt with last digit..
but i dont know why still got WA....
...
here is my code...where get bugs???

are all valid input pairs

Seems to work for me. What case doesn't it work for?

or give me an example where my program gives WA.

Would you use the [C++][/C++] code to format your program well in order to let other people read your program more easily?
Otherwise, other people can hardly help you.
