вернуться в форумTo xyz: I'm sorry to disturb you, but can you please tell me what's now wrong with my program Program Network; Const Max=100; Mr=Max*Max Div 2; Var i,j,n,k,p,v,st:Longint; a,b:Array[0..Mr] Of Longint; Begin a[0]:=0; b[0]:=0; For i:=1 To Mr Do Begin a[i]:=Max+1; For j:=3 To Max Do Begin v:=i-j*(j-1) Div 2; If v>=0 Then If a[v]+j<=a[i] Then Begin a[i]:=a[v]+j; b[i]:=j; End; End; End; Readln(n,k); k:=n*(n-1) Div 2 - k; If a[k]>n Then Writeln(-1) Else Begin p:=1; v:=k; While v>0 Do Begin st:=p; If st<>1 Then Writeln('1 ',st); For i:=1 To b[v]-1 Do Begin Writeln(p,' ',p+1); Inc(p); End; Writeln(p,' ',st); Inc(p); Dec(v,b[v]*(b[v]-1) Div 2); End; While p<=n Do Begin If p<>1 Then Writeln('1 ',p); Inc(p); End; End; End. AC at last! Thanks again, xyz! |
