如何从一个字符串中找到最小的字符串。换句话说,找到最小的字符串,使其可以连接多次以获得大字符串。

输入rbr 输出rb(我的函数工作正常)

另一个例子

输入 bcdbcdbcdbcd 输出:bcd(我的函数工作正常)

我试过这样的。

function getSmallestString(s){

let i= 0;
let tem = '';


while(true){
let mid = s.length/2;
let tem = s.substring(0,mid);
if(tem + tem == s){
s= tem
}else {
return s;
}

}

}

console.log('bcdbcdbcdbcd')

这里我的案例失败了

function getSmallestString(s){

let i= 0;
let tem = '';


while(true){
let mid = Math.floor(s.length/2);
let tem = s.substring(0,mid);
if(tem + tem == s){
s= tem
}else {
return s;
}

}

}

console.log(getSmallestString('ooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo'))

预期输出是o

在这种情况下,每个答案都失败了 lrbb 预期输出 lrbb

最佳答案

function getSmallestString(str) {
var current = "";
for(var i = 0, len = str.length; i < len; ++i) {
current += str[i];
if(str.replace(new RegExp(current,"g"),"") == "") return current
}
}
