while(cin>>n && n!=EOF)
{
bool pqBool = true;
int c=0,v=0, q=0,st=0, j=0, k =0, pq =0, aLength=0, sLength=0 ...

Why I got wrong answeer. please help anyone

using namespace std;

int main ()
{
int i, j, t, x, m, n, a[10]={0};
cin>>t;
while(t--)
{
scanf("%d:%d",&m,&n);
x = 100*m+n;
while(1)
{

First sort the value then check it.
"Do not think think about the property (a+b+c)>d(for this problem) only check (a+b+c)>=d. although it can not make a quadrangle"

For this problem the uvatoolkit also give the wrong answer.
