Problem Statement :

Bob participated in N Quizzes. Each quiz consists of M questions. Given an N X M matrix results where results[i][j] = 1 if Bob answered jth question correctly in the ith Quiz.

Each correct answer gives 10 marks and he has the option to select any quiz session for the marks evaluation.

What is the maximum marks Bob can get in a quiz? Input First line contains N and M. Next N lines contain M integers each.

Constraints 1 ≤ N, M ≤ 1000 results[i][j] = 0 or 1 Output A single integer denotes maximum marks. Example Input: 3 4 0 0 1 0 1 0 1 0 1 0 1 1
