Code with this:
    for (int i=0; i<n; i++)
    {
        int t;
        scanf("%li", &t);
    ...
gives wa1

Code with this:
    for (int i=0; i<n; i++)
    {
        int t;
        cin >> t;
    ...
gives tl36.
 Help, please, if know what is the problem

Use scanf("%d", &t). There is 32bit compilers.

Tried, result is exactly the same: wa1
