这篇博客介绍了CodeForces 961-A题目的模拟过程，讨论了类似俄罗斯方块的问题，其中玩家在n列平台上放置m个方块，每列至少有一个方块时，底部一行会消除并得分。博客内容包括问题描述、输入输出格式、样例输入输出以及解题思路和代码实现。通过模拟找到最小相同数的个数来计算得分。

Problem Description

You are given a following process.

There is a platform with n columns. 1×1 squares are appearing one after another in some columns on this platform. If there are no squares in the column, a square will occupy the bottom row. Otherwise a square will appear at the top of the highest square of this column.

When all of the n columns have at least one square in them, the bottom row is being removed. You will receive 1 point for this, and all the squares left will fall down one row.

The first line of input contain 2 integer numbers n and m (1≤n,m≤1000) — the length of the platform and the number of the squares.

The next line contain mm integer numbers c1,c2,…,cm (1≤ci≤n) — column in which i-th square w
