const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void async function () {
    
    while(line = await readline()){
        const len = line.length;
        if (len % 8 !== 0) {
            /* n: 对字符串的长度除以8 向下取整再加1 可以得知终止条件值
             如：字符串长度为22，算得n等于3，
             3 * 8 == 24
             24 - 22 == 2
             于是需要在字符串末尾补充2个0
             */
            const n = Math.floor(len / 8) + 1;
            for (let i = len; i < 8 * n; i++) {
                line += 0;
            }
        }
        while (line.length > 0) {
		    // 每8位打印一次
            console.log(line.slice(0,8));
			// 对字符串重新赋值
            line = line.slice(8);
