1.

var readline = require(‘readline‘);

const rl = readline.createInterface({

input: process.stdin,

output: process.stdout,

terminal:false

});

 

rl.on(‘line‘, function(line){ // javascript每行数据的回调接口

console.log(num(line));

});

 

function num(str){

var len = 0;

var s = new Set(str.split(‘‘));

if(s.size<=2) len = s.size;

return len;

}
