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 $10^{8}$.

Input

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

Output

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.
