Matrix and Chef

CodeChefRating 2350Open on judge ↗

Chef and his friend Miron were getting bored and decided to play a game. Miron thinks of a sequence of N integers (A1, A2, …., AN) and gives Chef a matrix B, where Bi,j = |Ai - Aj|. He further tells Chef that A1 = 0. The game is for Chef to guess the sequence that Miron thought of. But Miron is an adversarial player. Every time Chef tries to guess the sequence, he makes a change to the matrix.
