Problem: You are given a directed acyclic graph (a directed graph that does not contain cycles) of n vertices and m arcs. The i-th arc leads from the vertex x_i to the vertex y_i and has the weight w_i.

Your task is to select an integer a_v for each vertex v, and then write a number b_i on each arcs i such that b_i = a_{x_i} - a_{y_i}. You must select the numbers so that:

  * all b_i are positive; 
  * the value of the expression ∑ _{i = 1}^{m} w_i b_i is the lowest possible. 



It can be shown that for any directed acyclic graph with non-negative w_i, such a way to choose numbers exists.

Input

The first line contains two integers n and m (2 ≤ n ≤ 18; 0 ≤ m ≤ (n(n - 1))/(2)).

Then m lines follow, the i-th of them contains three integers x_i, y_i and w_i (1 ≤ x_i, y_i ≤ n, 1 ≤ w_i ≤ 10^5, x_i ≠ y_i) — the description of the i-th arc.

It is guaranteed that the lines describe m arcs of a directed acyclic graph without multiple arcs between the same pair of vertices.

Output

Print n integers a_1, a_2, ..., a_n (0 ≤ a_v ≤ 10^9), which must be written on the vertices so that all b_i are positive, and the value of the expression ∑ _{i = 1}^{m} w_i b_i is the lowest possible. If there are several answers, print any of them. It can be shown that the answer always exists, and at least one of the optimal answers satisfies the constraints 0 ≤ a_v ≤ 10^9.
