forloop双层循环闭眼算法，完整代码如下：
while (line = readline()) {
let maxLen = 0;
for (let i = 0; i < line.length; i++) {
for (let j = i+1; j < line.length; j++) {
let str = line.slice(i, j+1);
if ( str == str.split('').reverse().join('') && str.length > maxLen) {
maxLen = str.length;
}
}
}
console.log(maxLen);
}
