For each vertice of given undirected weighted graph calculate the length of shortest simple cycle, which contains this vertice.

Input

First line of the input contains one inteter n — number of vertices in the graph (1 ≤ n ≤ 300).

Each of n lines contain n integers, i-th integer in the i-th column is equal to 0 for any i. If for i ≠ j j-th integer in i-th line aij is equal to  - 1, then vertices i and j are not connected, otherwise they are connected by the edge of weight aij (1 ≤ aij ≤ 106).

You may assume that graph does not contain self-loops and aij = aji for any 1 ≤ i, j ≤ n.

Output

Print n integers one per line. i-th of those integers must be lentgh of the shortest simple cycle, containig i-th vertice. If no simple cycles contain i-th vertiex, print  - 1 at corresponding line.
