back to boardCommon BoardWhy WA??? I'm think, what my programm is right!!! Problem 1123 This is my program: Program n1123; Var a:array [0..2001] of char; n,i:word; pr:boolean; Begin a[0]:=' '; n:=0; While Ord(a[n])<>26 Do Begin n:=n+1; Read(a[n]); End; n:=n-1; pr:=true; If n<>1 Then Begin For i:=n downto (n div 2) Do Begin If a[i]>a[n+1-i] Then pr:=false Else If a[i]<a[n+1-i] Then pr:=true; a[i]:=a[n+1-i]; End; If Not pr Then Begin i:=(n div 2)+(n mod 2); Repeat If a[i]='9' Then Begin a[i]:='0'; If n+1-i<>i Then a[n+1-i]:='0'; End Else Begin a[i]:=Chr(Ord(a[i])+1); If n+1-i<>i Then a[n+1-i]:=Chr(Ord(a[n+1-i])+1); Break; End; Dec(i); Until false; End; End; For i:=1 to n Do Write(a[i]); WriteLn; End. Re: Read disscus border! Your program is wrong on Rybak Michael.(+) Try this input: 119921.
Your program will output 129921,
while the correct answer is 120021.
Good luck!

Re: Sorry. Your program work wrigth on the test. Your error: in input there are some symbols ' '(space[code 32]).Input can end with symbols #10,#13,#26.
