下面是生成程序:
const
n=100;
fm=200;
fz=198;
var
t,p,q:longint;
l:array[1..n,1..n]of byte;
begin
randomize;
fillchar(l,sizeof(l),0);
for t:=1 to n do
for p:=t+1 to n do
begin
q:=random(fm);
if q>fz then
begin
l[t,p]:=1;
l[p,t]:=1;
end;
end;
writeln(n);
for t:=1 to n do
begin
for p:=1 to n do
if l[t,p]=1 then write(p,’ ‘);
writeln(0);
end;
end.
希望对大家有帮助~
