// YOU ARE ACTUALLY **SUPPOSED** TO READ THE FOLLOWING.
// No need to hurry. Relax.
// Read Problems Carefully. (Please do this, you keep making mistakes because you avoided this.)
// Read both the input sizes (i.e. n <= 1e5, etc) and the sum of n thing. (i.e. sum of n <= 1e6, etc).
// Be Careful about input data size. You keep inputting data as int, when long long was required.
// Don't force some technique on a problem. BS does not solve everything. On many occasions, greedy rules.
// Declare double values as long double or ld (NEVER double, because of precision issues)
