CF417E.Square Table

While resting on the ship after the "Russian Code Cup" a boy named Misha invented an interesting game. He promised to give his quadrocopter to whoever will be the first one to make a rectangular table of size n × m, consisting of positive integers such that the sum of the squares of numbers for each row and each column was also a square.

Since checking the correctness of the table manually is difficult, Misha asks you to make each number in the table to not exceed 108.

在“俄罗斯编程杯”比赛结束后，一名叫米沙的男孩在船上休息时发明了一个有趣的游戏。他承诺将他的四旋翼飞行器奖励给第一个构造出一个 $n \times m$ 的矩形表格的人——该表格由正整数组成，且每一行与每一列中各数的平方和也均为完全平方数。

由于手动验证表格的正确性十分困难，米沙要求你构造的表格中每个数均不超过 $10^8$。

The first line contains two integers n and m (1 ≤ n, m ≤ 100) — the size of the table.

第一行包含两个整数 $n$ 和 $m$（$1 \leq n, m \leq 100$）—— 表格的尺寸。

Print the table that meets the condition: n lines containing m integers, separated by spaces. If there are multiple possible answers, you are allowed to print anyone. It is guaranteed that there exists at least one correct answer.

输出满足以下条件的表格：包含 n 行，每行含 m 个整数，整数之间用空格分隔。若存在多种可能的答案，输出任意一种即可。保证至少存在一个正确答案。
