作业帮前端实习二面面经
1.自我介绍
2.介绍下项目
3.vue双向绑定，缺陷，vue3的改进
4.算法：二叉树深度, var和let的区别
5.算法题：单次合并，当时程序没有运行成功，后来检查是一个地方单词拼写错了，最后的返回结果没有拼接
function WordsMerge(Words) {
if (Words.length <= 1) {
return JSON.stringify(Words);
} else {
let prev = [...Words[0]];
let i = 1;
while ( i < Words.length) {
let cur = [...Words[i]];
while (prev.length && cur.length && prev[prev.length - 1] === cur[0]) {
prev.pop();
cur.shift();
}
if (prev.concat(cur)) {
prev = prev.concat(cur);
i++;
} else {
prev = Words[i+1];
i += 2;
}
}
return JSON.stringify(prev.join(''))
}
}
var words = ['aab', 'bac', 'ccd', 'dde', 'efg'];
var res = WordsMerge(words);
console.log(res); // "acdfg"
