2738번: 행렬 덧셈

const input = require('fs')
	.readFileSync('./dev/stdin')
	.toString()
	.split('\n')
	.map((v) => v.split(' ').map(Number));

const [N, M] = input.shift();
let answer = Array.from(Array(N), () => Array(M).fill(0));
for (let i = 0; i < N; i++) {
	for (let j = 0; j < M; j++) {
		answer[i][j] = input[i][j] + input[i + N][j];
	}
}
console.log(answer.map((v) => v.join(' ')).join('\n'));
