笨办法

let line
while(line = readline()){
    let str = line;
    let arr = str.match(new RegExp(/[0-9]+/,'g'));
    let shortStr = ''
    let result = ''
    if(Array.isArray(arr)){
        arr.forEach(item=>{
            let index = str.indexOf(item)
            result+=str.substring(0,index);
            result+=`*${item}*`
            str = str.substring(index + item.length,str.length)
        });
        
    }
    result+=str
    console.log(result)
}
